Cdk2 Gene Summary [Rat]
Enables cyclin binding activity and cyclin-dependent protein serine/threonine kinase activity. Involved in several processes, including DNA synthesis involved in mitotic DNA replication; cellular response to insulin stimulus; and liver regeneration. Located in nucleus. Used to study membranoproliferative glomerulonephritis. Biomarker of interstitial cystitis. Human ortholog(s) of this gene implicated in prostate cancer and renal cell carcinoma. Orthologous to human CDK2 (cyclin dependent kinase 2). [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 rat Cdk2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
