Poli Gene Summary [Mouse]
Enables DNA-directed DNA polymerase activity. Acts upstream of or within cellular response to UV-C and translesion synthesis. Predicted to be located in cytoplasmic ribonucleoprotein granule and nuclear speck. Is expressed in brain; metanephros; primary spermatocyte; spermatid; and testis. Orthologous to human POLI (DNA polymerase iota). [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 Poli often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
