a member of the highly conserved cyclin family, whose members are characterized by a dramatic periodicity in protein abundance through the cell cycle. Cyclins function as regulators of CDK kinases. Expressed in all tissues tested. This cyclin binds and activates CDC2 or CDK2 kinases, and thus promotes both cell cycle G1/S and G2/M transitions. Note: This description may include information from UniProtKB.
Protein type: Nuclear receptor co-regulator
Cellular Component: nucleoplasm; male pronucleus; cytoplasm; female pronucleus; nucleus
