Abstract p27 binds and inhibits cyclin-CDK to arrest the cell cycle. p27 also regulates other processes including migration and development independent of its CDK inhibitory action. p27 is an atypical tumor suppressor: deletion or mutational inactivation of the gene encoding p27, CDKN1B, is rare in human cancers.
