Pola1 Gene Summary [Mouse]
Enables DNA-directed DNA polymerase activity. Involved in DNA replication initiation and DNA replication, synthesis of 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, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Pola1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
