Pcna Gene Summary [Rat]
Enables nuclear estrogen receptor binding activity. Involved in several processes, including cellular response to hydrogen peroxide; estrous cycle; and liver regeneration. Located in nucleus. Biomarker of several diseases, including brain ischemia (multiple); liver cancer (multiple); mucositis; obstructive jaundice; and sciatic neuropathy. Human ortholog(s) of this gene implicated in ataxia-telangiectasia-like disorder-2. Orthologous to human PCNA (proliferating cell nuclear antigen).

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