Cyclin-dependent kinase inhibitor 1C (CDKN1C)

Potent tight-binding inhibitor of several G1 cyclin/CDK complexes (cyclin E-CDK2, cyclin D2-CDK4, and cyclin A-CDK2) and, to lesser extent, of the mitotic cyclin B-CDC2. Negative regulator of cell proliferation.

May play a role in maintenance of the non- proliferative state throughout life. .
