Protein Information
Name CCND1
Synonyms BCL1, PRAD1
Function Regulatory component of the cyclin D1-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 D1/CDK4/CDKN1B, required for nuclear translocation and activity of the cyclin D-CDK4 complex. Exhibits transcriptional corepressor activity with INSM1 on the NEUROD1 and INS promoters in a cell cycle-independent manner.
Cellular Location Nucleus. Cytoplasm. Membrane. Note=Cyclin D-CDK4 complexes accumulate at the nuclear membrane and are then translocated to the nucleus through interaction with KIP/CIP family members

Cyclin D1 belongs to the Cyclin D family. Cyclin D1 is required for the cell cycle G1/S transition (1). Cyclin D1 forms a serine/threonine kinase holoenzyme complex with and functions as a regulatory subunit of CDK4 or CDK6. Cyclin D1 also phosphorylates and inactivates the retinoblastoma protein and promotes progression through the G1/S phase (2-3). Amplification or overexpression of cyclin D1 plays a pivotal role in the development of various human cancers including parathyroid adenoma, breast cancer, colon cancer, lymphoma, melanoma, and prostate cancer (4). Over-expression of cyclin D1 is known to correlate with the early onset of cancer and risk of tumor progression and metastasis (5). Cyclin D1 also associates with, and regulates the activity of transcription factors, coactivators and corepressors that govern histone acetylation and chromatin remodeling proteins (6-7)
