WebDec 13, 2024 · The intrinsically disordered proteins p21 and p27 are commonly known as CDK inhibitors, yet CDK4-CycD requires p21 or p27 (p21/p27) for assembly and activity in vivo. Moreover, all approved CDK4/6 inhibitors were developed against purified CDK4/6-CycD complexes that lacked p21/p27. p21 is a potent cyclin-dependent kinase inhibitor (CKI). The p21 (CIP1/WAF1) protein binds to and inhibits the activity of cyclin-CDK2, -CDK1, and -CDK4/6 complexes, and thus functions as a regulator of cell cycle progression at G1 and S phase. The binding of p21 to CDK complexes occurs through p21's N-terminal domain, which is homologous to the other CIP/KIP CDK inhibitors p27 and p57. Specifically it contains a Cy1 motif in the N-terminal half, and weaker Cy2 motif in the C-ter…
