WebCyclin-dependent kinases are defined as protein kinases whose kinase activities are depended on binding to a cyclin subunit. All CDKs are related in sequence to the … WebThe eukaryotic cell cycle is regulated by the temporal activation of different cyclin-dependent kinase (CDK)/cyclin complexes. Whilst the level of the catalytic subunit of the complex, the CDK, remains relatively constant through the cycle, the level of the cyclin subunit generally oscillates.

WebThe cell cycles in the tissues of higher animal and plant cells are controlled by a range of external hormones and other factors, and it was not surprising that a clock located somewhere in an animal should affect the cell cycles in its tissues. WebCyclins control the transition between the phases of the eukaryotic cell cycle as regulatory subunits of the cyclin-dependent kinases (CDKs). Phase-specific activation of the CDK is in part regulated by phase-specific expression of their cyclin component.
