Summary: Predicted to enable several functions, including MDM2/MDM4 family protein binding activity; NF-kappaB 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, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
