Abstract
Replicative DNA polymerases, such as DNA polymerase α-primase, δ and ε, are multi-subunit complexes that are responsible for the bulk of nuclear DNA replication during the S phase. Over the last decade, extensive genome-wide association studies and expression profiling studies of the replicative DNA polymerase genes in human patients have revealed a link between the replicative DNA polymerase genes and various human diseases and disorders including cancer, intellectual disability, microcephalic primordial dwarfism and immunodeficiency. These studies suggest the importance of dissecting the mechanisms involved in the functioning of replicative DNA polymerases in understanding and treating a range of human diseases. Previous studies in Drosophila have established this organism as a useful model to understand a variety of human diseases. Here, we review the studies on Drosophila that explored the link between DNA polymerases and human disease. First, we summarize the recent studies linking replicative DNA polymerases to various human diseases and disorders. We then review studies on replicative DNA polymerases in Drosophila. Finally, we suggest the possible use of Drosophila models to study human diseases and disorders associated with replicative DNA polymerases.

Abstract
DNA synthesis during replication or repair is a fundamental cellular process that is catalyzed by a set of evolutionary conserved polymerases. Despite a large body of research, the DNA polymerases of Drosophila melanogaster have not yet been systematically reviewed, leading to inconsistencies in their nomenclature, shortcomings in their functional (Gene Ontology, GO) annotations and an under-appreciation of the extent of their characterization. Here, we describe the complete set of DNA polymerases in D. melanogaster, applying nomenclature already in widespread use in other species, and improving their functional annotation. A total of 19 genes encode the proteins comprising three replicative polymerases (alpha-primase, delta, epsilon), five translesion/repair polymerases (zeta, eta, iota, Rev1, theta) and the mitochondrial polymerase (gamma). We also provide an overview of the biochemical and genetic characterization of these factors in D. melanogaster. This work, together with the incorporation of the improved nomenclature and GO annotation into key biological databases, including FlyBase and UniProtKB, will greatly facilitate access to information about these important proteins.

Abstract
The Drosophila DNAprim gene encodes the large subunit (60 kD) of DNA primase, the part of DNA polymerase alpha that synthesizes RNA primers during DNA replication. The precise function of the 60-kD subunit is unknown. In a mutagenesis screen for suppressors of the fat facets (faf) mutant eye phenotype, we identified mutations in DNAprim. The faf gene encodes a deubiquitinating enzyme required specifically for patterning the compound eye. The DNA sequences of four DNAprim alleles were determined and these define essential protein domains. We show that while flies lacking DNAprim activity are lethal, flies with reduced DNAprim activity display morphological defects in their eyes, and unlike faf mutants, cell cycle abnormalities in larval eye discs. Mechanisms by which DNA primase levels might influence the faf-dependent cell communication pathway are discussed.

Abstract
We have cloned the gene for the large subunit of the DNA primase from Drosophila melanogaster, and mapped it to position 77b on chromosome 3. The central region of the protein shows high similarity with homologues from other species, but the N- and C-termini diverge. The protein is enriched in replicating tissues, and consistent with this the region upstream of the gene contains close matches to the sites of two transcription factors - Dref and E2f - which have been implicated in controlling proliferation-associated genes.

Abstract
DNA polymerase epsilon (pol epsilon) from HeLa cells was purified to near homogeneity, utilizing Mono S fast protein liquid chromatography for complete separation from pol alpha. The purified pol epsilon preparation showed two polypeptides of > 200 and 55 kDa and a small amount of active 122-kDa proteolysis product on denaturing polyacrylamide gels. Pol epsilon (as well as pols alpha and delta) is optimally active in 100-150 mM potassium glutamate and 15 mM MgCl2. Replication factors RF-A and RF-C, proliferating cell nuclear antigen, and Escherichia coli single-stranded DNA binding protein showed no significant effect on this preparation's pol epsilon activity, processivity, or substrate specificity. The size of the pol epsilon transcript for the catalytic subunit (> 200 kDa) was investigated in both normal human fibroblasts and HeLa cells. A 7.7-kilobase transcript was detected which was 5-16-fold more prevalent in proliferating than in quiescent HeLa cells. No significant difference in the level of pol epsilon transcript in HeLa cells or fibroblasts was seen after ultraviolet irradiation. Mouse polyclonal antiserum was produced to a 144-amino acid fragment of pol epsilon fused to staphylococcal protein A. This non-neutralizing polyclonal antiserum specifically recognized the catalytic subunit of pol epsilon by immunoblotting, but not that of pol alpha, beta, or delta. In addition, mouse polyclonal antiserum raised against column-purified pol epsilon was able to recognize and to neutralize pol epsilon, and a mouse monoclonal antibody was raised which was able to recognize specifically the catalytic subunit of pol epsilon.

Abstract
The past decade has witnessed an exciting evolution in our understanding of eukaryotic DNA replication at the molecular level. Progress has been particularly rapid within the last few years due to the convergence of research on a variety of cell types, from yeast to human, encompassing disciplines ranging from clinical immunology to the molecular biology of viruses. New eukaryotic DNA replicases and accessory proteins have been purified and characterized, and some have been cloned and sequenced. In vitro systems for the replication of viral DNA have been developed, allowing the identification and purification of several mammalian replication proteins. In this review we focus on DNA polymerases alpha and delta and the polymerase accessory proteins, their physical and functional properties, as well as their roles in eukaryotic DNA replication.

Abstract
ts A1S9 mutant cells, derived from wild type WT-4 mouse L-cells, are temperature-sensitive (ts) for DNA synthesis and cell division. We try to determine the cause of the arrest of DNA replication in ts A1S9 cells at the nonpermissive temperature by comparing the modifications induced by the shift of temperature on the activity and the synthesis of DNA polymerase-alpha and DNA primase as a function of time. Forty-seven hours after temperature upshift DNA polymerase-alpha activity of ts A1S9 cells was inhibited by 90% while primase activity was barely detectable. By contrast, the activities of both enzymes increased to a plateau level in WT-4 cultured at either temperature and in ts A1S9 cells grown at the low permissive temperature. Study of the synthesis of DNA polymerase-alpha primase and of the structure of the enzyme complex during cell cycle progression was approached by immunoprecipitation of [35S]-labelled cells, with a specific monoclonal antibody directed against DNA polymerase-alpha. We have found that, irrespective of temperature of cultivation of WT-4 or ts A1S9 cells, this antibody precipitated polypeptides of 220, 186, 150, 110, 68-70, 60, and 48 kDa from cell extracts. With ts A1S9 cells cultivated at 38.5 degrees C for 48 hr the polypeptides of 220 and 186 kDa, associated with alpha-polymerase activity, were considerably more abundant than in the control cells, with a concomitant decline in the polypeptides of 60 and 48 kDa, implicated in primase activity. Thus the inhibition of DNA polymerase-alpha cannot be due to a decreased synthesis of the 186 kDa subunit but to its temperature inactivation. Consistent with a recent asymmetric dimeric model where polymerase-alpha complex and polymerase delta complex synthesize co-ordinately at the replication fork lagging and leading DNA strands, the observed alterations of polymerase-alpha and primase content explain the inhibition of DNA synthesis and the cell cycle arrest of the ts A1S9 cells at the nonpermissive temperature.

Abstract
Two species of DNA polymerase alpha free of primase activity were identified in extracts of Ehrlich mouse cells that had been infected with minute virus of mice. Primase-free forms of DNA polymerase alpha eluted with 150 and 180 mM NaCl during ion-exchange chromatography on DEAE-cellulose columns, exhibited sedimentation coefficients of 11 S and 8.2 S, respectively, and were inhibited by aphidicolin, N2-(p-n-butylphenyl)-9-(2-deoxy-beta-D-ribofuranosyl)guanine 5'-triphosphate, and 2-(p-n-butylanilino)-9-(2-deoxy-beta-D-ribofuranosyl)adenine 5'-triphosphate. The ratio of primase-free DNA polymerase alpha to the DNA polymerase alpha-primase complex increased from 1.5 to greater than 100 during the course of infection, and free primase was produced during the MVM replicative cycle.
