Pole3 Gene Summary [Mouse]
Predicted to enable chromatin DNA binding activity. Predicted to be involved in several processes, including chromatin remodeling; leading strand elongation; and regulation of nucleobase-containing compound metabolic process. Located in pericentric heterochromatin. Is expressed in several structures, including alimentary system; cranium; genitourinary system; nervous system; and sensory organ. Orthologous to human POLE3 (DNA polymerase epsilon 3, accessory 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 Pole3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- histone-fold domain
- histone fold domain (HFD) superfamily
- DNA-directed DNA polymerase
