Background
| Function | FUNCTION: Important regulator of cell cycle progression. Inhibits the kinase activity of CDK2 bound to cyclin A, but has little inhibitory activity on CDK2 bound to SPDYA (PubMed:28666995). Involved in G1 arrest. Potent inhibitor of cyclin E- and cyclin A-CDK2 complexes. Forms a complex with cyclin type D-CDK4 complexes and is involved in the assembly, stability, and modulation of CCND1-CDK4 complex activation. Acts either as an inhibitor or an activator of cyclin type D-CDK4 complexes depending on its phosphorylation state and/or stoichometry. {ECO:0000269|PubMed:10831586, ECO:0000269|PubMed:12244301, ECO:0000269|PubMed:16782892, ECO:0000269|PubMed:17254966, ECO:0000269|PubMed:19075005, ECO:0000269|PubMed:28666995}. |
