Splet05. apr. 2024 · In the cytoplasm, CDK7 contains the core of CDK activated kinase (CAK). Moreover, CAK is a trimeric complex, which also contains CDK7 specific binding chaperones, cyclin H, and MAT1. Inhibition of CDK7 resulted in the accumulation of G1 or G2/M cells and a decrease in the number of S-phase cells. A 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.
