POLA1 - DNA polymerase alpha 1, catalytic subunit Gene

Homo sapiens

Also known as NSX; POLA; p180; VEODS

Gene ID: 5422 | Gene type: protein coding

About POLA1

Cytogenetic location: Xp22.11-p21.3 Genomic coordinates (GRCh38): X:24,693,918-24,996,986 (from NCBI)

This gene has 14 transcripts (splice variants), 197 orthologues, 3 paralogues and is associated with 7 phenotypes. Ubiquitous expression in lymph node (RPKM 2.6), bone marrow (RPKM 2.2) and 25 other tissues.

Summary

This gene encodes the catalytic subunit of DNA Polymerase, which together with a regulatory and two primase subunits, forms the DNA Polymerase alpha complex. The catalytic subunit plays an essential role in the initiation of DNA replication. [provided by RefSeq, Mar 2010]
