This article is about the cell cycle protein. For the medical therapy, see CDK inhibitor.

A cyclin-dependent kinase inhibitor protein is a protein which inhibits cyclin-dependent kinase. Several function as tumor suppressor genes. Cell cycle progression is negatively controlled by cyclin-dependent kinases inhibitors (called CDIs, CKIs or CDKIs). CDIs are involved in cell cycle arrest at the G1 phase.
