Polm Gene Summary [Rat]
Predicted to enable DNA-directed DNA polymerase activity. Predicted to be involved in double-strand break repair via nonhomologous end joining. Predicted to act upstream of or within B cell differentiation and somatic hypermutation of immunoglobulin genes. Predicted to be active in nucleus. Orthologous to human POLM (DNA polymerase mu).

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