CDK-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. WebApr 13, 2024 · Aberrant activity of cyclin-dependent kinase (Cdk5) has been implicated in various neurodegenerative diseases. This deleterious effect is mediated by pathological cleavage of the Cdk5 activator p35 into the truncated product p25, leading to prolonged Cdk5 activation and altered substrate specificity.

WebCell division and apoptosis are key aspects of cancer biology. Cdk (cyclin-dependent kinase) associates with cyclins to form Cdk-cyclin complexes, which play a crucial role in cell cycle progression.
