Gene type: protein coding
RefSeq status: VALIDATED
Organism: Rattus norvegicus
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; Myomorpha; Muroidea; Muridae; Murinae; Rattus
Also known as: p15
Summary: Predicted to enable cyclin-dependent protein serine/threonine kinase inhibitor activity and protein kinase binding activity. Involved in several processes, including cellular response to transforming growth factor beta stimulus; negative regulation of cell cycle G1/S phase transition; and negative regulation of glial cell proliferation. Predicted to be active in cytoplasm and nucleus. Used to study endometrial cancer and renal cell carcinoma. Human ortholog(s) of this gene implicated in carcinoma (multiple); erythema infectiosum; hematologic cancer (multiple); open-angle glaucoma; and urinary bladder cancer. Orthologous to human CDKN2B (cyclin dependent kinase inhibitor 2B). [provided by Alliance of Genome Resources, Nov 2024]
Expression: Biased expression in Lung (RPKM 105.6), Adrenal (RPKM 45.9) and 5 other tissues See more

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.
