A cyclin-dependent kinase inhibitor (CKI) is a protein that interacts with a cyclin-CDK complex to block kinase activity, usually during G1 or in response to signals from the environment or from damaged DNA. [1] In animal cells, there are two major CKI families: the INK4 family and the CIP/KIP family. [1] Visa mer Cyclin-dependent kinases (CDKs) are the families of protein kinases first discovered for their role in regulating the cell cycle. They are also involved in regulating transcription, mRNA processing, and the differentiation of … Visa mer CDK levels remain relatively constant throughout the cell cycle and most regulation is post-translational. Most knowledge of CDK … Visa mer Diseases of CDK As drug targets CDKs are considered a potential target for anti-cancer medication.

Cellular Signalling. 17 (9): 1033–51. Visa mer Most of the known cyclin-CDK complexes regulate the progression through the cell cycle. Animal cells contain at least nine CDKs, four of which, CDK1, 2, 3, and 4, are directly involved in cell cycle regulation. In mammalian cells, CDK1, with its partners … Visa mer Leland H. Hartwell, R. Timothy Hunt, and Paul M.
