Abstract
Vaccine‐specific antibody responses are essential in the diagnosis of antibody deficiencies. Responses to Pneumovax II are used to assess the response to polysaccharide antigens, but interpretation may be complicated. Typhim Vi®, a polysaccharide vaccine for Salmonella typhoid fever, may be an additional option for assessing humoral responses in patients suspected of having an immunodeficiency. Here we report a UK multi‐centre study describing the analytical and clinical performance of a Typhi Vi immunoglobulin (Ig)G enzyme‐linked immunosorbent assay (ELISA) calibrated to an affinity‐purified Typhi Vi IgG preparation. Intra‐ and interassay imprecision was low and the assay was linear, between 7·4 and 574 U/ml (slope = 0·99–1·00; R2 > 0·99); 71% of blood donors had undetectable Typhi Vi IgG antibody concentrations. Of those with antibody concentrations > 7·4 U/ml, the concentration range was 7·7–167 U/ml. In antibody‐deficient patients receiving antibody replacement therapy the median Typhi Vi IgG antibody concentrations were < 25 U/ml. In vaccinated normal healthy volunteers, the median concentration post‐vaccination was 107 U/ml (range 31–542 U/ml). Eight of eight patients (100%) had post‐vaccination concentration increases of at least threefold and six of eight (75%) of at least 10‐fold. In an antibody‐deficient population (n = 23), only 30% had post‐vaccination concentration increases of at least threefold and 10% of at least 10‐fold. The antibody responses to Pneumovax II and Typhim Vi® correlated. We conclude that IgG responses to Typhim Vi® vaccination can be measured using the VaccZyme Salmonella typhi Vi IgG ELISA, and that measurement of these antibodies maybe a useful additional test to accompany Pneumovax II responses for the assessment of antibody deficiencies.

Abstract
BACKGROUND Active TB disease can destroy lung parenchyma leading to cavities. Immune responses that predispose or protect individuals from lung damage during TB are poorly defined. OBJECTIVE To sample lung immune cells and assay bronchoalveolar lavage (BAL) cell cytokine production. DESIGN Enrolled subjects (n = 73) had bilateral infiltrates and underwent BAL. RESULTS All had sputum culture demonstrating Mycobacterium tuberculosis and 22/73 (30%) had cavities on their chest radiograph. Those with cavities at presentation had a higher percentage of polymorphonuclear neutrophils (PMN) in BAL as well as lower inducible protein (IP) 10 (P < 0.01) and interleukin (IL) 6 (P = 0.013) in BAL cell supernatants compared to those without cavities. There was no correlation between cavities and other BAL or serum cytokines. IP-10 was negatively associated with BAL PMN. IP-10 and IL-6 expression above median reduces the odds of cavities by 79% and 78% in logistic regression models. IP-10 and IL-6 clustered with interferon-gamma and tumour necrosis factor-alpha in a principal component analysis, while IL-4 clustered with PMN. CONCLUSION Increasing IP-10 and IL-6 production by BAL cells is associated with non-cavitary TB in patients who present with radiographically advanced TB. IP-10 and IL-6 may reflect an effective T-helper 1 immune control pathway for TB, attenuating tuberculous lung destruction.

Abstract
OBJECTIVE To assess the current use of glucocorticoids (GCs) in Duchenne muscular dystrophy in the UK, and compare the benefits and the adverse events of daily versus intermittent prednisolone regimens. DESIGN A prospective longitudinal observational study across 17 neuromuscular centres in the UK of 360 boys aged 3-15 years with confirmed Duchenne muscular dystrophy who were treated with daily or intermittent (10 days on/10 days off) prednisolone for a mean duration of treatment of 4 years. RESULTS The median loss of ambulation was 12 years in intermittent and 14.5 years in daily treatment; the HR for intermittent treatment was 1.57 (95% CI 0.87 to 2.82). A fitted multilevel model comparing the intermittent and daily regiments for the NorthStar Ambulatory Assessment demonstrated a divergence after 7 years of age, with boys on an intermittent regimen declining faster (p<0.001). Moderate to severe side effects were more commonly reported and observed in the daily regimen, including Cushingoid features, adverse behavioural events and hypertension. Body mass index mean z score was higher in the daily regimen (1.99, 95% CI 1.79 to 2.19) than in the intermittent regimen (1.51, 95% CI 1.27 to 1.75). Height restriction was more severe in the daily regimen (mean z score -1.77, 95% CI -1.79 to -2.19) than in the intermittent regimen (mean z score -0.70, 95% CI -0.90 to -0.49). CONCLUSIONS Our study provides a framework for providing information to patients with Duchenne muscular dystrophy and their families when introducing GC therapy. The study also highlights the importance of collecting longitudinal natural history data on patients treated according to standardised protocols, and clearly identifies the benefits and the side-effect profile of two treatment regimens, which will help with informed choices and implementation of targeted surveillance.

Abstract
Although interferon-γ release assays (IGRAs) are intended for diagnosing latent tuberculosis (TB), we hypothesised that in a high-burden setting: 1) the magnitude of the response when using IGRAs can distinguish active TB from other diagnoses; 2) IGRAs may aid in the diagnosis of smear-negative TB; and 3) IGRAs could be useful as rule-out tests for active TB. We evaluated the accuracy of two IGRAs (QuantiFERON®-TB Gold In-tube (QFT-GIT) and T-SPOT®.TB) in 395 patients (27% HIV-infected) with suspected TB in Cape Town, South Africa. IGRA sensitivity and specificity (95% CI) were 76% (68-83%) and 42% (36-49%) for QFT-GIT and 84% (77-90%) and 47% (40-53%) for T-SPOT®.TB, respectively. Although interferon-γ responses were significantly higher in the TB versus non-TB groups (p<0.0001), varying the cut-offs did not improve discriminatory ability. In culture-negative patients, depending on whether those with clinically diagnosed TB were included or excluded from the analysis, the negative predictive value (NPV) of QFT-GIT, T-SPOT®.TB and chest radiograph in smear-negative patients varied between 85 and 89, 87 and 92, and 98% (for chest radiograph), respectively. Overall accuracy was independent of HIV status and CD4 count. In a high-burden setting, IGRAs alone do not have value as rule-in or -out tests for active TB. In smear-negative patients, chest radiography had better NPV even in HIV-infected patients.

Abstract
For the prevention and control of non-communicable diseases (NCD), an action plan on NCDs is intended to support coordinated, comprehensive and integrated implementation of strategies and evidence-based interventions across individual diseases and risk factors, especially at the national and regional levels by World Health Organization (WHO). The Global Alliance against Chronic Respiratory Diseases (GARD) is making every attempt to align with WHO's non-communicable diseases action plan. GARD activities have been commenced in over 40 countries and in 11 countries an integrated NCD action plan is being prepared or has already been initiated. This integrated approach of GARD has also targeted to GARD Turkey project. The Turkish Ministry of Health has decided to apply this national control program in conformity with other NCD action plans. This article is intended to summarize these integration efforts of GARD Turkey (the National Control Program on Chronic Airway Diseases) with other NCD national programs.

Abstract
In order to prevent and control non-communicable diseases (NCDs), the 61st World Health Assembly has endorsed an NCD action plan (WHA resolution 61.14). A package for essential NCDs including chronic respiratory diseases (CRDs) has also been developed. The Global Alliance against Chronic Respiratory Diseases (GARD) is a new but rapidly developing voluntary alliance that is assisting World Health Organization (WHO) in the task of addressing NCDs at country level. The GARD approach was initiated in 2006. GARD Turkey is the first comprehensive programme developed by a government with all stakeholders of the country. This paper provides a summary of indicators of the prevalence and severity of chronic respiratory diseases in Turkey and the formation of GARD Turkey.

Abstract
BACKGROUND South Africa recently launched a national antiretroviral treatment programme. This has created an urgent need for nurse-training in antiretroviral treatment (ART) delivery. The PALSA PLUS programme provides guidelines and training for primary health care (PHC) nurses in the management of adult lung diseases and HIV/AIDS, including ART. A process evaluation was undertaken to document the training, explore perceptions regarding the value of the training, and compare the PALSA PLUS training approach (used at intervention sites) with the provincial training model. The evaluation was conducted alongside a randomized controlled trial measuring the effects of the PALSA PLUS nurse-training (Trial reference number ISRCTN24820584). METHODS Qualitative methods were utilized, including participant observation of training sessions, focus group discussions and interviews. Data were analyzed thematically. RESULTS Nurse uptake of PALSA PLUS training, with regard not only to ART specific components but also lung health, was high. The ongoing on-site training of all PHC nurses, as opposed to the once-off centralized training provided for ART nurses only at non-intervention clinics, enhanced nurses' experience of support for their work by allowing, not only for ongoing experiential learning, supervision and emotional support, but also for the ongoing managerial review of all those infrastructural and system-level changes required to facilitate health provider behaviour change and guideline implementation. The training of all PHC nurses in PALSA PLUS guideline use, as opposed to ART nurses only, was also perceived to better facilitate the integration of AIDS care within the clinic context. CONCLUSION PALSA PLUS training successfully engaged all PHC nurses in a comprehensive approach to a range of illnesses affecting both HIV positive and negative patients. PHC nurse-training for integrated systems-based interventions should be prioritized on the ART funding agenda. Training for individual provider behaviour change is nonetheless only one aspect of the ongoing system-wide interventions required to effect lasting improvements in patient care in the context of an over-burdened and under-resourced PHC system.

Abstract
BACKGROUND Diagnosis of childhood tuberculosis is problematic and symptom based diagnostic approaches are often promoted in high burden settings. This study aimed (i) to document the prevalence of symptoms associated with tuberculosis among randomly selected children living in a high burden community, and (ii) to compare the prevalence of these symptoms in children without tuberculosis to those in children with newly diagnosed tuberculosis. METHODS A cross sectional, community based survey was performed on a 15% random sample of residential addresses. A symptom based questionnaire and tuberculin skin test (TST) were completed in all children. Chest radiographs were performed according to South African National Tuberculosis Control Program guidelines. RESULTS Results were available in 1415 children of whom 451 (31.9%) were TST positive. Tuberculosis was diagnosed in 18 (1.3%) children. Of the 1397 children without tuberculosis, 253 (26.4%) reported a cough during the preceding 3 months. Comparison of individual symptoms (cough, dyspnoea, chest pain, haemoptysis, anorexia, weight loss, fatigue, fever, night sweats) in children with and without tuberculosis revealed that only weight loss differed significantly (OR = 4.5, 95% CI 1.5 to 12.3), while the combination of cough and weight loss was most significant (OR = 5.4, 95% CI 1.7 to 16.9). Children with newly diagnosed tuberculosis reported no symptoms in 50% of cases. CONCLUSION Children from this high burden community frequently reported symptoms associated with tuberculosis. These symptoms had limited value to differentiate children diagnosed with tuberculosis from those without tuberculosis. Improved case definitions and symptom characterisation are required when evaluating the diagnostic value of symptoms.

Abstract
We have developed a solid-phase enzyme-linked immunosorbent assay (ELISA) to study the vaccination responses to Vi capsular polysaccharide of Salmonella typhi (S. typhi Vi) vaccine. Purified S. typhi Vi polysaccharide was biotinylated and bound to streptavidin coated microtitre plates. Reproducibility was determined across a range of IgG antibody levels: mean interassay coefficients of variation (CVs) were <11.9% for non-vaccinated sera with low levels and <11.1% for sera with very high levels of anti-S. typhi Vi IgG. Specificity was assessed by inhibition studies using salmonella antigen. We have developed the ELISA based on normal adult serum responses to test immunization with S. typhi Vi vaccine. We also report here anti-S. typhi Vi IgG levels in a group of healthy preschool children. In non-vaccinated adult sera (n = 104), the median value of anti-S. typhi Vi IgG, expressed in S. typhi Vi arbitrary units (AU/ml), was 5.3 AU/ml and in non-vaccinated sera from children (n = 44) the median value was 1.4 AU/ml. The data from immunization of healthy volunteers (n = 23) show that geometric mean levels of anti-S. typhi Vi IgG were significantly higher (P < 0.0001) for post-vaccination subjects (39.2 AU/ml) compared to paired prevaccination (3.9 AU/ml) values. A total of 21/23 vaccine recipients had <8 AU/ml S. typhi Vi IgG in their sera prior to vaccination and of these 20/21 (95%) exhibited threefold increases and 14/21 (67%) fourfold increases in their S. typhi Vi IgG following vaccination. Based on the data in this study, we propose a threefold increase in anti-S. typhi Vi IgG post-vaccination to be considered a positive vaccination response. The ability to demonstrate clearly an antibody rise in response to immunization with S. typhi Vi capsular polysaccharide vaccine suggests that this is likely to be a useful vaccine for the assessment of B cell function in patients with suspected immune deficiency.

Abstract
The transcription activator TATA box-binding protein promoter-binding factor (TPBF) is both an activator and repressor of TBP gene expression in Acanthamoeba. TPBF bears little similarity to previously characterized families of factors. In order to identify domains that are involved in DNA binding, activation, and repression, we constructed several alanine linker scanning mutants and tested them for their ability to function in a variety of assays. The DNA binding domain comprises a large 100-amino acid domain within the central third of the protein, suggesting that DNA recognition is accomplished by interactions derived from several structural units within this domain. Surprisingly, transcription activation and repression are impaired by mutations within either of two discrete amino acid sequences located on either side of the DNA binding domain. These data suggest that TPBF activation and repression are accomplished by interactions with the same target. Since TATA elements can function bidirectionally, and in solution TBP can bind to TATA elements in either orientation, we propose that TPBF functions in part by orienting TBP or TFIID correctly on the TATA box.

Abstract
The effects of distamycin A on Acanthamoeba transcription, growth and differentiation were determined. Distamycin A inhibits transcription both in vitro and in vivo and can displace from DNA the transcription activator TATA binding protein promoter binding factor (TPBF). Inhibition in vivo is surprisingly selective for large rRNA precursors, 5S rRNA, profilin, S-adenosylmethionine synthetase, and extendin. Transcription from the TATA binding protein (TBP), TPBF, protein disulfide isomerase, tubulin and RNA polymerase II large subunit genes is only slightly inhibited. Moreover the rate of 5S rRNA transcription eventually recovers and exceeds that of untreated cells, while profilin transcription remains inhibited. Distamycin A inhibition is accompanied by a complex pattern of alterations to steady state levels of mRNAs. Actin, profilin and S-adenosylmethionine synthetase mRNAs are degraded, whereas mRNA encoding TBP is increased slightly in abundance. Transcription inhibition is accompanied by cessation of growth and severe morphological changes to Acanthamoeba, which are consistent with loss of production of mRNA encoding cytoskeletal proteins. Distamycin A also prevents starvation-induced differentiation of Acanthamoeba, in part due to complete prevention of cellulose production and cell wall formation.

Abstract
The rates of transcription of several protein coding genes during Acanthamoeba differentiation have been examined by nuclear run-on and RNase protection assays. During early encystment, transcription by RNA polymerase II increases approximately 4-fold, whereas transcription by RNA polymerases I and III is decreased, as previously described. The rates of transcription from a wide variety of individual genes are only slightly affected during the first 16 h of encystment, although profilin gene expression is markedly increased. The levels of mRNAs encoding TPBF, TATA binding protein, cyclin-dependent kinase, protein disulfide isomerase, profilin, myosin II heavy chain, ubiquitin and extendin are stable during mature cyst formation, whereas mRNAs encoding actin, S-adenosyl methionine synthase and tubulin are substantially decreased in abundance within 16 h of starvation-induced encystment. We conclude that in contrast to the negative regulation of large rRNA and 5S rRNA synthesis during differentiation, the RNA polymerase II transcription apparatus is not negatively regulated. Control of Acanthamoeba differentiation is likely to be mediated by positive regulation of genes necessary for cyst maturation.

Abstract
The structures of several promoters regulating the expression of eukaryotic transcription factors have in recent years been examined. In many cases there is good evidence for autoregulation, in which a given factor binds to its own promoter and either activates or represses transcription. Autoregulation occurs in all eukaryotes and is an important component in controlling expression of basal, cell cycle specific, inducible response and cell type-specific factors. The basal factors are autoregulatory, being strictly necessary for their own expression, and as such must be epigenetically inherited. Autoregulation of stimulus response factors typically serves to amplify cellular signals transiently and also to attenuate the response whether or not a given inducer remains. Cell cycle-specific transcription factors are positively and negatively autoregulatory, but this frequently depends on interlocking circuits among family members. Autoregulation of cell type-specific factors results in a form of cellular memory that can contribute, or define, a determined state. Autoregulation of transcription factors provides a simple circuitry, useful in many cellular circumstances, that does not require the involvement of additional factors, which, in turn, would need to be subject to another hierarchy of regulation. Autoregulation additionally can provide a direct means to sense and control the cellular conce]ntration of a given factor. However, autoregulatory loops are often dependent on cellular pathways that create the circumstances under which autoregulation occurs.

Abstract
Transcription of the Acanthamoeba TATA-binding protein (TBP) gene is regulated by TBP promoter-binding factor (TPBF), a previously described transactivator that binds as a tetramer to the TBP Promoter Element (TPE) and stimulates transcription up to 10-fold in vitro. Here we report that TPBF also functions as a transcription repressor by binding to a negative cis-element, located between the TATA box and the transcription initiation site. The negative element, referred to as the nTPE, is structurally similar to the TPE, and its disruption increases the transcription potency of the TBP promoter. TPBF binds to the nTPE, as demonstrated by mobility shift assays. However, the binding affinity of TPBF for the nTPE is about 10-fold lower than for the TPE. When placed upstream of the TATA box, the nTPE has very little effect on transcription. However, it inhibits transcription when placed at several positions downstream of the TATA box. Mechanistic studies with the TBP promoter suggest that binding of TPBF to the nTPE not only prevents TBP from binding to the TATA box but also displaces bound TBP, thereby inhibiting further assembly of the preinitiation complex. These results suggest a mechanism in which the cellular TPBF concentration controls the level of TBP gene transcription and show that a single factor can be stimulatory, inhibitory, or neutral depending on the sequence and the context of its binding site.

Abstract
Eukaryotic promoter elements specify the direction and efficiency of transcription, as well as the type of RNA polymerase to be used. One such element, the TATA box, is thought to participate in determining the direction of transcription and can function within promoters for RNA polymerase II or III, depending on the sequence context. In this report the ability of four different TATA boxes to support transcription in vitro was determined. It was found that TATA elements are not directional. However, they support transcription by RNA polymerases II and III. An upstream activating sequence was found to stimulate downstream transcription by RNA polymerase II and to inhibit upstream transcription by RNA polymerases II and III. Thus a promoter necessarily consists of a TATA element and upstream sequences in order to specify the direction of transcription and the type of polymerase to be used.

Abstract
TATA-binding protein (TBP) gene promoter binding factor (TPBF) is a transactivator which binds to the TBP promoter element (TPE) sequence of the Acanthamoeba TBP gene promoter and stimulates transcription in vitro. We have isolated a cDNA clone encoding TPBF. TPBF is a polypeptide of 327 amino acids with a calculated molecular mass of 37 kDa. The predicted amino acid sequence of TPBF shows no significant homology to other proteins. TPBF has two potential coiled-coil regions, a basic region, a proline-rich region, a histidine-rich N terminus, and a nuclear targeting sequence. The recombinant protein has an apparent molecular mass of 50 kDa, identical with that of TPBF purified from Acanthamoeba. Recombinant TPBF is able to bind DNA and activate transcription with the same specificity as natural Acanthamoeba TPBF, demonstrating the authenticity of the clone. Mobility shift assays of co-translated TPBF polypeptides and chemical cross-linking demonstrate that TPBF is tetrameric in solution and when bound to DNA. Analyses of TPBF mutants show that Coiled-coil II is essential for DNA binding, but Coiled-coil I and the basic region are also involved. TPBF is thus a novel DNA-binding protein with functional similarity to the tumor suppressor protein p53.

Abstract
We have cloned, from Acanthamoeba castellanii, the cDNA encoding a new member of the protein disulfide isomerase (PDI)-like protein family. The new PDI-like protein contains two highly conserved thioredeoxin-like domains, each about 100 amino acids in length. However, the A. castellanii PDI-like protein differs from other members in many aspects, including the overall organization and isoelectric point. Southern and Northern analyses demonstrate that the PDI-like protein is encoded by a single-copy gene which is transcribed to generate a 1500-nucleotide mRNA.

Abstract
Transcription of the Acanthamoeba tbp gene is stimulated by a cis-acting promoter element that is bound by an activator protein, TATA-binding protein promoter binding factor (TPBF). Here, we report the complete purification of TPBF and describe its transcription activating and DNA-binding properties. TPBF contains two polypeptides with molecular weights of 51,000 and 50,000, whereas the native molecular weight of TPBF suggests it is dimeric or trimeric in solution. Phosphatase treatment of TPBF converts the 51,000 molecular weight species to the 50,000 molecular weight form, demonstrating that TPBF is phosphorylated. Phosphorylation reduces DNA binding by TPBF, as assessed by electrophoretic mobility shift assays after phosphatase treatment. TPBF makes numerous contacts with the bases and phosphate backbone of its DNA recognition element, and the pattern of these contacts suggests that it is a novel type of DNA-binding protein. TPBF can bind to additional, low affinity sites within the TBP gene promoter, suggesting that, in addition to positive activation of tbp gene expression, TPBF could also inhibit transcription by competing for binding sites for other proteins within the TBP promoter.

Abstract
In this report, we test the hypothesis that TBP binds DNA promiscuously due to its manner of recognition of the DNA minor groove. The experiment performed was to select TBP-binding sequences from a pool of random double stranded oligonucleotides. Sixty two clones from this pool were sequenced. Surprisingly, the results show that TBP has a marked preference for stably binding one sequence (TATATAA) over all others, yet only four classes of TATA box were selected. The features of the selected sequences allow definition of a binding consensus for TBP. The DNA binding properties of TBP to the four TATA variants was examined, the results being in accord with the observed selection frequencies. However, the nature of TBP-DNA binding is strongly affected by ionic strength. We infer that recognition of DNA via the minor groove can be highly selective even where A:T and T:A discrimination is required. Models for how this might be accomplished are discussed.

Abstract
The role of the Acanthamoeba castellanii TATA-binding protein (TBP) in transcription was examined. Specific antibodies against the nonconserved N-terminal domain of TBP were used to verify the presence of TBP in the fundamental transcription initiation factor for RNA polymerase I, TIF-IB, and to demonstrate that TBP is part of the committed initiation complex on the rRNA promoter. The same antibodies inhibit transcription in all three polymerase systems, but they do so differentially. Oligonucleotide competitors were used to evaluate the accessibility of the TATA-binding site in TIF-IB, TFIID, and TFIIIB. The results suggest that insertion of TBP into the polymerase II and III factors is more similar than insertion into the polymerase I factor.

Abstract
We have characterized a positive-acting element in the upstream portion of the Acanthamoeba TBP gene promoter. The 27 bp element (TPE), located within the promoter between -97 and -70, stimulates transcription in an orientation independent fashion and tolerates modest changes in its distance from the TATA box. The TPE does not, however, function synergistically nor when positioned 3000 bp 5' or 260 base pairs 3' of the transcription start site. The TPE binds a DNA sequence-dependent factor, TPBF, which we have partly purified. TPBF was characterized using in vitro transcription, DNase I footprinting, methylation interference and electrophoretic mobility shift assays. TPBF does not have a counterpart in HeLa cells, but nonetheless strongly stimulates transcription of the Acanthamoeba TBP gene in mammalian extracts. Our results also suggest that there are additional positively and negatively acting elements within the TBP gene promoter, for which a model is presented.

Abstract
We have developed and characterized an efficient in vitro system from the protozoan, Acanthamoeba castellanii, that accurately initiates transcription from the adenovirus-2 major late promoter (AdMLP). Transcription by A. castellanii RNA polymerase II (pol II) is initiated at the same nucleotide (nt) that is used by HeLa extracts and is dependent upon adenovirus sequences located between nt -51 and the region around the transcription start point (tsp). The results suggest that the A. castellanii transcription factors for pol II which determine the tsp and the promoter elements that they recognize have been functionally conserved during evolution.

Abstract
We have isolated a genomic clone encoding Acanthamoeba castellanii TFIID. The clone contains the entire TFIID gene, 300 bp of 5' promoter sequences and several hundred base pairs of 3' non-coding sequence. The coding region is interrupted by two short introns, but is otherwise identical to Acanthamoeba TFIID cDNA. Comparisons between forty four Acanthamoeba intron 5' and 3' boundaries suggest a 5' splice site consensus of GTACG(T/C) and a 3' consensus of CAG. We determined the position of the transcription initiation site used in vivo, and show that the same site is used in vitro by homologous nuclear extracts. Deletion analysis of the promoter region shows that the minimal promoter required for efficient expression in vitro is located between -97 and +4 relative to the transcription start site. Three regions within the promoter are important for transcription in vitro; sequences between -97 and -35, the TATAAA box and the initiation region. The initiation region is dispensable but appears to position the transcription start site relative to the TATAAA box. The TATAAA box is absolutely required for transcription initiation whereas the upstream region stimulates transcription approximately five-fold.

Abstract
We have cloned and characterized the cDNA encoding transcription factor TFIID from the eukaryote, Acanthamoeba castellanii. The gene occurs as a single species, encodes one mRNA and, presumably, a single protein. A. castellanii TFIID contains two recognizable domains, a nonconserved N-terminal domain and a highly conserved C-terminal domain. Similarities between the amino acid (aa) sequences of TFIID from several organisms are also found within the N-terminal 78 aa, suggesting a potential role in TFIID function. Full-length or truncated A. castellanii TFIID produced in Escherichia coli binds to a TATA box and is able to activate transcription in a TFIID-depleted HeLa cell extract, but the C-terminal 180-aa domain was found to be less efficient in these reactions.
