WebA cyclin-dependent kinase complex ( CDKC, cyclin-CDK) is a protein complex formed by the association of an inactive catalytic subunit of a protein kinase, cyclin-dependent kinase (CDK), with a regulatory subunit, cyclin. [1] Once cyclin-dependent kinases bind to cyclin, the formed complex is in an activated state. WebCyclin-dependent kinases (CDKs) trigger the transition from G1 to S phase and from G2 to M phase by phosphorylating distinct sets of substrates. (B) CDK1 and CDK2 bind to …
