WebJun 29, 2024 · 1. Introduction. Cell cycle control relies on the rapid formation and disassembly of regulatory protein complexes. At the core of the cell cycle machinery is the family of cyclin-dependent kinases (Cdks; reviewed in []) whose members are activated by binding a cyclin subunit.Cyclin B1 binds and activates Cdk1 to form the major mitotic … WebCyclin B1 and B2 can localize Cdk1 to the nucleus and the Golgi, respectively, through a localization sequence outside the CDK-binding region. [1] Phosphorylation [ edit] Cyclin binding alone causes partial activation of Cdks, but complete activation also requires activating phosphorylation by a CAK.
