The gene DNA polymerase α 50kD is referred to in FlyBase by the symbol Dmel\DNApol-α50 (CG7108, FBgn0011762). It is a protein_coding_gene from Drosophila melanogaster. Based on sequence similarity, it is predicted to have molecular function: DNA-directed DNA polymerase activity. There is experimental evidence that it is involved in the biological process: DNA replication; neurogenesis. 5 alleles are reported. No phenotypic data is available. It has one annotated transcript and one annotated polypeptide. Protein features are: DNA primase, small subunit; DNA primase, small subunit, eukaryotic/archaeal. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderately high expression to a trough of very low expression. Peak expression observed within 00-06 hour embryonic stages. Summary of FlyAtlas Anatomical Expression Data: Expression at moderate levels in the following post-embryonic organs or tissues: adult ovary. Comments on Affy2 ProbeSet: ProbeSet 1633854_at completely aligns to an exonic region of the only FlyBase-annotated transcript isoform of DNApol-alpha50. Gene sequence location is 3L:8333420..8337504.

Please Note
This section lists
cDNAs and ESTs that fall within the genomic extent
of the gene model, which may include cDNAs and ESTs
of genes within introns, or of overlapping genes.
Please see GBrowse for alignment of the cDNAs and ESTs
to the gene model.
DNApol-α50 has been cloned and characterised. Expression patterns of DNApol-α50 protein and transcript throughout development are consistent with a role of the protein in DNA replication.
25bp DNA oligomer containing m4T is used in a gel extension assay to measure the efficiency of incorporation of dATP and dGTP opposite m4T using a DNA polymerase α-primase complex. The DNA polymerase α shows a clear preference for pairing with dGTP.
