P16 protein function
p16 (also known as p16 , cyclin-dependent kinase inhibitor 2A, CDKN2A, multiple tumor suppressor 1 and numerous other synonyms), is a protein that slows cell division by slowing the progression of the cell cycle from the G1 phase to the S phase, thereby acting as a tumor suppressor. It is encoded by the … See more p16 is also known as: • p16 • p16 • Cyclin-dependent kinase inhibitor 2A (CDKN2A) • CDKN2 See more p16 is an inhibitor of cyclin-dependent kinases (CDK). It slows down the cell cycle by prohibiting progression from G1 phase to S phase. Otherwise, CDK4/6 binds cyclin D and forms an … See more Role in carcinogenesis Mutations resulting in deletion or reduction of function of the CDKN2A gene are associated with increased risk of a wide range of cancers, and alterations of the gene are frequently seen in cancer cell lines. … See more Researchers Manuel Serrano, Gregory J.
