Abstract / Description of output
A common event in the development of human neoplasia is the inactivation of a damage-inducible cell-cycle checkpoint pathway regulated by p53. One approach to the restoration of this pathway is to mimic the activity of key downstream effectors. The cyclin-dependent kinase (Cdk) inhibitor p21(WAF1) is one such molecule, as it is a major mediator of the p53-dependent growth-arrest pathway, and can, by itself, mediate growth suppression. The primary function of the p21(WAF1) protein appears to be the inhibition of G1 cyclin-Cdk complexes. Thus, if we can identify the region(s) of p21(WAF1) that contain its inhibitor activity they may provide a template from which to develop novel anti-proliferative drugs for use in tumours with a defective p53 pathway.
