Phosphorylation of cyclin
WebJan 15, 1999 · The cyclin binding domain of CDC6 was mapped to an N-terminal Cy-motif that is similar to the cyclin binding regions in p21 WAF1/SDI1 and E2F-1. The in vivo phosphorylation of CDC6 was dependent on three N-terminal CDK consensus sites, and the phosphorylation of these sites was shown to regulate the subcellular localization of … WebThe cyclin-dependent kinases (CDKs) are a family of serine/threonine kinases controlling progression through the cell cycle.1The regulatory subunits of the CDKs, known as cyclins, form complexes with their catalytic partner to function as checkpoint kinases of specific proteins that regulate progression through the cell cycle.
