Cyclins function as regulators of CDK kinases. Different cyclins exhibit distinct expression and degradation patterns which contribute to the temporal coordination of each mitotic event. This cyclin forms a complex with CDK4 or CDK6 and functions as a regulatory subunit of the complex, whose activity is required for cell cycle G1/S transition. This protein has been shown to interact with and be involved in the phosphorylation of tumor suppressor protein Rb. Knockout studies of the homologous gene in mouse suggest the essential roles of this gene in ovarian granulosa and germ cell proliferation. High level expression of this gene was observed in ovarian and testicular tumors. Mutations in this gene are associated with megalencephaly-polymicrogyria-polydactyly-hydrocephalus syndrome 3 (MPPH3).

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. Hypophosphorylates RB1 in early G(1) phase. Cyclin D-CDK4 complexes are major integrators of various mitogenenic and antimitogenic signals. Also substrate for SMAD3, phosphorylating SMAD3 in a cell-cycle-dependent manner and repressing its transcriptional activity. Component of the ternary complex, cyclin D2/CDK4/CDKN1B, required for nuclear translocation and activity of the cyclin D-CDK4 complex (By similarity). {ECO:0000250}. |Cyclin C| |Cyclin N| |cyclin-dependent protein kinase holoenzyme complex| |positive regulation of cyclin-dependent protein serine/threonine kinase activity| |cyclin-dependent protein serine/threonine kinase regulator activity| |positive regulation of cyclin-dependent protein kinase activity| |positive regulation of G1/S transition of mitotic cell cycle| |positive regulation of cell cycle G1/S phase transition| |positive regulation of mitotic cell cycle phase transition| |positive regulation of cell cycle phase transition| |regulation of cyclin-dependent protein serine/threonine kinase activity| |regulation of cyclin-dependent protein kinase activity| |chromatin| |regulation of G1/S transition of mitotic cell cycle| |positive regulation of mitotic cell cycle| |regulation of cell cycle G1/S phase transition| |protein kinase activity| |nuclear membrane| |mitotic cell cycle phase transition| |cell cycle phase transition| |positive regulation of cell cycle process| |positive regulation of protein serine/threonine kinase activity| |positive regulation of cell cycle| |regulation of mitotic cell cycle phase transition| |regulation of cell cycle phase transition| |protein kinase binding| |cell division| |regulation of protein serine/threonine kinase activity| |positive regulation of protein kinase activity| |positive regulation of kinase activity| |mitotic cell cycle process| |regulation of mitotic cell cycle| |positive regulation of transferase activity| |mitotic cell cycle| |regulation of cell cycle process| |regulation of protein kinase activity| |nucleolus| |regulation of kinase activity| |negative regulation of apoptotic process| |negative regulation of programmed cell death| |positive regulation of cell population proliferation| |protein phosphorylation| |regulation of transferase activity| |negative regulation of cell death| |cell cycle process| |positive regulation of protein phosphorylation| |positive regulation of phosphorylation| |positive regulation of phosphorus metabolic process| |positive regulation of phosphate metabolic process| |regulation of cell cycle| |positive regulation of protein modification process| |phosphorylation| |cell cycle| |positive regulation of catalytic activity| |regulation of protein phosphorylation| |regulation of apoptotic process| |regulation of programmed cell death| |regulation of phosphorylation| |positive regulation of cellular protein metabolic process| |regulation of cell population proliferation| |regulation of cell death| |positive regulation of protein metabolic process| |positive regulation of molecular function| |regulation of phosphate metabolic process| |regulation of phosphorus metabolic process| |regulation of protein modification process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp302|35°C R06 exp302]]|-2.52| |[[:results:exp282|Fluvastatin 2.2μM R06 exp282]]|-2.49| |[[:results:exp483|FTY720 3μM R08 exp483]]|-2.23| |[[:results:exp477|DKK1 89ng/ml R08 exp477]]|-1.9| |[[:results:exp216|Erlotinib 10μM R05 exp216]]|-1.9| No correlation found to any other genes in chemogenomics.
