Target Details for p21

Target: p21 (CDKN1A) (Cyclin-Dependent Kinase Inhibitor 1A (p21, Cip1) (CDKN1A))

Alternative Name: p21

Background: P21 belongs to a class of tumor suppressors including p16 and p27 which control progression through the cell cycle by inhibiting the activity of cyclin-cdk complexes. p21 is also known as senescent cell-derived inhibitor 1 (Sdi1), wild-type p53-activated fragment 1 (Waf1), Cdk-interacting protein 1 (Cip1), p21 and p53-regulated inhibitor of Cdks (Pic1). p21 mRNA is expressed at higher levels in senescent fibroblasts than in actively growing cells. When introduced into proliferating foreskin fibroblasts, p21 inhibits DNA synthesis and cell cycle arrest. p53 can activate p21 gene expression via a p53 binding site identified in the promoter of the p21 gene.
