CDKN2B - cyclin dependent kinase inhibitor 2B Gene
Also Known as P15; MTS2; TP15; CDK4I; INK4B; p15INK4b
Species: Homo sapiens
About CDKN2B
This gene has 3 transcripts (splice variants), 95 orthologues, 1 paralogue and is associated with 2 phenotypes. Broad expression in colon (RPKM 20.3), small intestine (RPKM 17.6) and 17 other tissues.
Summary
This gene lies adjacent to the tumor suppressor gene CDKN2A in a region that is frequently mutated and deleted in a wide variety of tumors. This gene encodes a cyclin-dependent kinase inhibitor, which forms a complex with CDK4 or CDK6, and prevents the activation of the CDK kinases, thus the encoded protein functions as a cell growth regulator that controls cell cycle G1 progression. The expression of this gene was found to be dramatically induced by TGF beta, which suggested its role in the TGF beta induced growth inhibition. Two alternatively spliced transcript variants of this gene, which encode distinct proteins, have been reported. [provided by RefSeq, Jul 2008]
