Protein Information (annotations from UniProt)

Database IDHIV0008484
UniProt IDP30279
Primary gene name(s)CCND2
Synonym gene name(s)unknown
Protein nameG1/S-specific cyclin-D2
Protein functionRegulatory 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. 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}.
Subcellular locationNucleus {ECO:0000269|PubMed:18827403}. Cytoplasm {ECO:0000269|PubMed:18827403}. Membrane {ECO:0000269|PubMed:18827403}. 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}.;
SUBCELLULAR LOCATION: Isoform 2: Cytoplasm {ECO:0000269|PubMed:17873913}.
