ID Q04827; PN G1/S-specific cyclin-D2; GN Ccnd2; OS 10116; SL Nucleus Position: SL-0178; SL Nucleus Position: SL-0182; SL Comments: Nucleus {ECO:0000250|UniProtKB:P30279}. Cytoplasm {ECO:0000250|UniProtKB:P30279}. Nucleus membrane {ECO:0000250|UniProtKB:P30279}. Note=Cyclin D-CDK4 complexes accumulate at the nuclear membrane and are then translocated into the nucleus through interaction with KIP/CIP family members. {ECO:0000250|UniProtKB:P30279}. DR UNIPROT: Q04827; DR Pfam: PF02984; DR Pfam: PF00134; DR PROSITE: PS00292; DE Function: 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. 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. {ECO:0000250|UniProtKB:P30279}.
