The CDK inhibitor 1 (also: p21 ) is an inhibitor of cyclin-dependent kinases ( C yclin d ependent k INASE), the essential for the control of the cell cycle in mammals is. Among other things, p21 suppresses cancer growth .
The gene coding for p21 is located in humans on chromosome 6 gene locus p21.2. p21 is mainly regulated by cells at the level of transcription . Induction of transcription of p21 leads to a standstill of the cell cycle, while inhibition of transcription leads to various effects, which depend on the context. p21 knockout mice develop normally by about 16 months of age. Then they start to develop tumors .
