This complex is functionally … the angel hotel gatesheadCDK-activating kinase (CAK) activates the cyclin-CDK complex by phosphorylating threonine residue 160 in the CDK activation loop. CAK itself is a member of the Cdk family and functions as a positive regulator of Cdk1, Cdk2, Cdk4, and Cdk6. See more Cdk activation requires two steps. First, cyclin must bind to the Cdk. In the second step, CAK must phosphorylate the cyclin-Cdk complex on the threonine residue 160, which is located in the Cdk activation segment. Since See more The conformation of the Cdk2 active site changes dramatically upon cyclin binding and CAK phosphorylation. The active site of Cdk2 lies in a cleft between the two lobes of the kinase.
