Symbol/Gene Name:  CDK3;CCNE1

Alias:  Cyclin-dependent kinase 3,Cell division protein kinase 3;G1/S-specific cyclin-E1

Uniprot: Q00526/P24864

Background: Serine/threonine-protein kinase that plays a critical role in the control of the eukaryotic cell cycle; involved in G0-G1 and G1-S cell cycle transitions. Interacts with CCNC/cyclin-C during interphase. Phosphorylates histone H1, ATF1, RB1 and CABLES1. ATF1 phosphorylation triggers ATF1 transactivation and transcriptional activities, and promotes cell proliferation and transformation. CDK3/cyclin-C mediated RB1 phosphorylation is required for G0-G1 transition. Promotes G1-S transition probably by contributing to the activation of E2F1, E2F2 and E2F3 in a RB1-independent manner.

Essential for the control of the cell cycle at the G1/S (start) transition.
