DESCRIPTION

Also known as CCND2_HUMAN, CCND2. Regulatory component of the cyclin D2-CDK4 (DC) complex that phosphorylates and inhibits members of the retinoblastoma (RB) protein family including RB1 and regulates the cell-cycle during G(1)/S transition (PubMed:8114739, PubMed:18827403). Phosphorylation of RB1 allows dissociation of the transcription factor E2F from the RB/E2F complex and the subsequent transcription of E2F target genes which are responsible for the progression through the G(1) phase (PubMed:8114739, PubMed:18827403). Hypophosphorylates RB1 in early G(1) phase (PubMed:8114739, PubMed:18827403). Cyclin D-CDK4 complexes are major integrators of various mitogenenic and antimitogenic signals (PubMed:8114739, PubMed:18827403). Interacts with either CDK4 or CDK6 protein kinase to form a serine/threonine kinase holoenzyme complex (PubMed:8114739, PubMed:18827403). The cyclin subunit imparts substrate specificity to the complex (PubMed:8114739, PubMed:18827403).
