Cyclin E is a member of the cyclin family. Cyclin E binds to G1 phase Cdk2, which is required for the transition from G1 to S phase of the cell cycle that determines initiation of DNA duplication. The Cyclin E/CDK2 complex phosphorylates p27 (an inhibitor of Cyclin D), tagging it for degradation, thus promoting expression of Cyclin A, allowing progression to S … WebApr 13, 2024 · Cyclin-dependent kinase 2 (Cdc2) is involved in the metabolic pathways of the cell cycle and plays essential roles in the regulation of cell proliferation in eukaryotic …

WebThe cyclin-dependent kinase Cdk2 associates with cyclins A, D, and E and has been implicated in the control of the G1 to S phase transition in mammals. To identify potential Cdk2 regulators, we have employed an improved two-hybrid system to isolate human genes encoding Cdk-interacting proteins (Cips). WebCyclin E1, the prototypic E-cyclin, was first described in 1991 [1], and has since been found to have crucial roles in cell proliferation and oncogenesis [2,3]. The second mammalian E-cyclin, cyclin E2, was identified in 1998 [4,5], and is largely regarded as being functionally redundant with cyclin E1 [2,3,6]. Cyclin E1 and cyclin
