Target Details for p21

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

Alternative Name: p21 / CDKN1A

Background: This mAb recognizes a 21  kDa protein, identified as the p21WAF1 tumor suppressor protein, expressed by the CDNK1A gene. This mAb is highly specific to CDNK1A/p21 and shows no cross-reaction with other closely related mitotic inhibitors. p21WAF1 is a specific inhibitor of cdk's and a tumor suppressor involved in the pathogenesis of a variety of malignancies. The expression of this gene acts as an inhibitor of the cell cycle during G1 phase and is tightly controlled by the tumor suppressor protein p53. Its expression is induced by the wild type, but not mutant, p53 suppressor protein. Normal cells generally display a rather intense nuclear p21 expression. Loss of CDNK1A expression has been reported in many carcinomas (gastric carcinoma, non-small cell lung carcinoma, thyroid carcinoma).
