External Ids for CDK3 Gene
This gene encodes a member of the cyclin-dependent protein kinase family. The protein promotes entry into S phase, in part by activating members of the E2F family of transcription factors. The protein also associates with cyclin C and phosphorylates the retinoblastoma 1 protein to promote exit from G0. [provided by RefSeq, Jul 2008]
GeneCards Summary for CDK3 Gene
CDK3 (Cyclin-Dependent Kinase 3) is a Protein Coding gene. Among its related pathways are Cell Cycle Control of Chromosomal Replication and GADD45 Pathway. GO annotations related to this gene include cyclin-dependent protein serine/threonine kinase activity. An important paralog of this gene is CDK1.
UniProtKB/Swiss-Prot for CDK3 Gene
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.
