Prim1 Gene Summary [Mouse]
Enables DNA-directed RNA polymerase activity. Involved in DNA replication initiation and DNA replication, synthesis of primer. Part of alpha DNA polymerase:primase complex. Is expressed in several structures, including alimentary system; brain; genitourinary system; respiratory system; and sensory organ. Orthologous to human PRIM1 (DNA primase subunit 1).

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 Prim1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
