ID:CDK3_HUMAN DESCRIPTION: RecName: Full=Cyclin-dependent kinase 3; EC=2.7.11.22; AltName: Full=Cell division protein kinase 3; FUNCTION: 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. CATALYTIC ACTIVITY: ATP + a protein = ADP + a phosphoprotein. SUBUNIT: Interacts with CABLES1 and CABLES2 (By similarity). Interacts with ATF1. Binding to CCNC/cyclin-C promotes RB1 phosphorylation. TISSUE SPECIFICITY: Expressed in cancer cell lines and glioblastoma tissue. SIMILARITY: Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. CDC2/CDKX subfamily. SIMILARITY: Contains 1 protein kinase domain. WEB RESOURCE: Name=NIEHS-SNPs; URL="http://egp.gs.washington.edu/data/cdk3/";
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
