WebCyclin-dependent kinase inhibitor 1B (CDKN1B), also known as p27, binds to and prevents the activation of CyclinE:Cdk2 by inhibition. However, as Cyclin A accumulates and binds to Cdk2, they form a complex and inhibit p27. The G1 phase cyclin-dependent kinase works together with S phase cyclin-dependent kinase targeting p27 for degradation. WebCdk1, in complex with cyclin B (Cdk1/cyclin B), is a negative regulator of cytokinesis and Cdk1/cyclin B catalytic activity must be switched off to allow initiation of cytokinesis (Potapova et al., 2006). In early mitosis, Cdk1/cyclin B activity is high to promote assembly of the mitotic apparatus and chromosome alignment.
