Cdkn2a Gene Summary [Rat]

Predicted to enable several functions, including DNA-binding transcription activator activity, RNA polymerase II-specific; MDM2/MDM4 family protein binding activity; and enzyme inhibitor activity. Involved in several processes, including cellular response to glucose stimulus; negative regulation of hepatocyte proliferation; and nervous system development. Predicted to be located in mitochondrion; nuclear lumen; and senescence-associated heterochromatin focus. Predicted to be part of protein-containing complex. Used to study carcinoma (multiple); endometrial cancer; pre-malignant neoplasm; rhabdomyosarcoma; and sarcomatoid mesothelioma. Biomarker of hepatocellular carcinoma; hypertension; obesity; and osteoarthritis. Human ortholog(s) of this gene implicated in several diseases, including breast cancer (multiple); carcinoma (multiple); hematologic cancer (multiple); melanoma (multiple); and pancreatic cancer (multiple). Orthologous to human CDKN2A (cyclin dependent kinase inhibitor 2A). [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 Cdkn2a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
