CDKN1A

A gene on chromosome 6p21.2 that encodes a cyclin-dependent kinase inhibitor, which binds to and inhibits the activity of cyclin-CDK2 or -CDK4 complexes, thus acting as a regulator of cell cycle progression at G1. CDKN1A expression is controlled by p53, a tumour suppressor that mediates p53-dependent cell cycle G1-phase arrest in response to various stress stimuli. CDKN1A is specifically cleaved by CASP3-like caspases, activating CDK2 and possibly also the apoptosis pathway.

Overexpression of cyclin-dependent kinase inhibitor 1 (WAF1) from the kinase inhibitor protein group and PAK-[gamma] (p21- activated kinase [gamma]), combined with overexpression of CDKN2D (p19-INK4D) and cell division protein kinase 3 (CDK3), denote a major derangement in the regulation of cell-cycle progression.
