Summary
Enables DNA-directed DNA polymerase activity. Involved in DNA replication, synthesis of RNA primer. Acts upstream of or within DNA replication. Located in nucleus. Part of alpha DNA polymerase:primase complex. Human ortholog(s) of this gene implicated in Van Esch-O'Driscoll syndrome and X-linked reticulate pigmentary disorder. Orthologous to human POLA1 (DNA polymerase alpha 1, catalytic subunit). [provided by Alliance of Genome Resources, Apr 2022]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
