Target Information
CDK4/cyclin D3 serine/threonine kinase is a dimeric protein complex. CDK4, a member of the cyclin-dependent protein kinase family, regulates cell proliferation during the G1 phase of the cell cycle. It forms a complex with D-type cyclins and is inhibited by p16 (cyclin-dependent kinase inhibitor-2). CDK4 mediates phosphorylation of the C-terminal region of the Rb protein, leading to transcriptional repression of the E2F complex. CDC37 and HSP90 preferentially associate with CDK4 not bound to D-type cyclins. SMAD3 serves as a physiological substrate for CDK4 and CDK2. Although both CDK4 and CDK6 phosphorylate Rb protein, they exhibit different residue selectivity—CDK6 phosphorylates Thr821, while CDK4 phosphorylates Thr826.
