Abstract
Proteasome subunit alpha type-2 (PSMA2) is a critical component of the 20S proteasome, which is the core particle of the 26S proteasome complex and is involved in cellular protein quality control by recognizing and recycling defective proteins. PSMA2 expression dysregulation has been detected in different human diseases and viral infections. No study yet has reported PSMA2 knockdown (KD) effects on the cellular proteome. METHODS We used SOMAScan, an aptamer-based multiplexed technique, to measure >1300 human proteins to determine the impact of PSMA2 KD on A549 human lung epithelial cells. RESULTS PSMA2 KD resulted in significant dysregulation of 52 cellular proteins involved in different bio-functions, including cellular movement and development, cell death and survival, and cancer. The immune system and signal transduction were the most affected cellular functions. PSMA2 KD caused dysregulation of several signaling pathways involved in immune response, cytokine signaling, organismal growth and development, cellular stress and injury (including autophagy and unfolded protein response), and cancer responses. CONCLUSIONS In summary, this study helps us better understand the importance of PSMA2 in different cellular functions, signaling pathways, and human diseases.

Abstract
The interferon regulatory factors (IRF) are transcriptional mediators of cellular response to viral invasion that play a critical role in the innate antiviral defense. Two of these factors, IRF-5 and IRF-7, play a critical role in the induction of interferon (IFNA) genes in infected cells; they are expressed constitutively in monocytes, B cells, and precursors of dendritic cells (pDC2) that are high producers of interferon alpha, and their expression can be further stimulated by type I interferon. The goal of the present study was to identify and analyze expression of cellular genes that are modulated by IRF-5 and IRF-7 during the innate response to viral infection. The transcription profiles of infected BJAB cells overexpressing IRF-5 or IRF-7 were determined by using oligonucleotide arrays with probe sets representing about 6800 human genes. This analysis shows that IRF-5 and IRF-7 activate a broad profile of heterologous genes encoding not only antiviral, inflammatory, and pro-apoptotic proteins but also proteins of other functional categories. The number of IRF-5- and IRF-7-modulated genes was significantly higher in infected than in uninfected cells, and the transcription signature was predominantly positive. Although IRF-5 and IRF-7 stimulated a large number of common genes, a distinct functional profile was associated with each of these IRFs. The noted difference was a broad antiviral and early inflammatory transcriptional profile in infected BJAB/IRF-5 cells, whereas the IRF-7-induced transcripts were enriched for the group of mitochondrial genes and genes affecting the DNA structure. Taken together, these data indicate that IRF-5 and IRF-7 act primarily as transcriptional activators and that IRF-5-and IRF-7-induced innate antiviral response results in a broad alteration of the transcriptional profile of cellular genes.

Abstract
BACKGROUND Pseudovitamin D-deficiency rickets is characterized by the early onset of rickets with hypocalcemia and is thought to be caused by a deficit in renal 25-hydroxyvitamin D3 1alpha-hydroxylase, the key enzyme for the synthesis of 1alpha,25-dihydroxyvitamin D3. METHODS We cloned human 25-hydroxyvitamin D3 1alpha-hydroxylase complementary DNA (cDNA) using a mouse 1alpha-hydroxylase cDNA fragment as a probe. Its genomic structure was determined, and its chromosomal location was mapped by fluorescence in situ hybridization. We then identified mutations in the 1alpha-hydroxylase gene in four unrelated patients with pseudovitamin D-deficiency rickets by DNA-sequence analysis. Both the normal and the mutant 1alpha-hydroxylase proteins were expressed in COS-1 cells and were assayed for 1alpha-hydroxylase activity. RESULTS The gene for 25-hydroxyvitamin D3 1alpha-hydroxylase was mapped to chromosome 12q13.3, which had previously been reported to be the locus for pseudovitamin D-deficiency rickets by linkage analysis. Four different homozygous missense mutations were detected in this gene in the four patients with pseudovitamin D-deficiency rickets. The unaffected parents and one sibling tested were heterozygous for the mutations. Functional analysis of the mutant 1alpha-hydroxylase protein revealed that all four mutations abolished 1alpha-hydroxylase activity. CONCLUSIONS Inactivating mutations in the 25-hydroxyvitamin D3 1alpha-hydroxylase gene are a cause of pseudovitamin D-deficiency rickets.

Abstract
Genomic clones were obtained for the genes encoding the beta subunits of the human proteasome and for the associated proteasome activators PA28alpha and beta (PSME1 and PSME2, respectively). Fluorescence in situ hybridization was used to map the gene encoding the beta subunit PSMB3 (beta3 hs, HsC10-II) to chromosome band 2q35, PSMB2 (beta4 hs, HsC7-I) to band 1p34.2, and PSMB4 (beta7 hs, HSBpros 26) to band 1q21. Genes encoding the alpha and beta subunits of the PA28 complex were found closely linked on chromosome band 14q11.2, within 1 Mb of the beta proteasome locus PSMB5 (beta5 hs, MB1, X). These data complete the mapping of the human proteasome beta subunit loci. With the exception of the genes encoding the PSMB9 and PSMB8 (LMP2 and LMP7, respectively) subunits, the beta genes were not closely linked in the human genome. Both PSMB2 and PSMB4 mapped to a region of chromosome 1 that is proposed to be paralogous to other regions of the human genome where beta proteasome genes map: chromosome 6 containing the major histocompatibility complex (MHC) and chromosome 9. The independent regulation of expression of all of these genes, implied by this study, is consistent with a key role for proteasome assembly in coordination of the complex.

Linkage of TATA-binding protein and proteasome subunit C5 genes in mice and humans reveals synteny conserved between mammals and invertebrates. Genomics 1997; 44:1-7.

Abstract
The TATA-binding protein (TBP) is a factor required for the transcription of all classes of eukaryotic genes. Here, we demonstrate that in the mouse the TBP-encoding gene (Tbp) resides next to the proteasomal subunit C5-encoding gene (Psmb1). The genes are located on mouse chromosome 17 in the t complex within the Hybrid sterility 1 (Hst1) region. We demonstrate that the homologous human genes (TBP AND PSMB1) are tightly linked on the long arm of chromosome 6, in a region syntenic with the proximal part of mouse chromosome 17. The mouse Tbp and Psmb1 and the human TBP and PSMB1 genes are transcribed in the opposite orientation. The TATA-binding protein and proteasomal subunit C5 genes are also linked on chromosome III of Caenorhabditis elegans, and together they are linked to other genes whose homologs map to human chromosome 6 and mouse chromosome 17. In the Drosophila genome, the housekeeping TATA-binding protein gene maps close to two other genes with homologs in the mammalian major histocompatibility complex. There thus exists conserved synteny of unrelated genes between mammals and invertebrates.
