Cyclin D1 belongs to the Cyclin D family. Cyclin D1 is required for the cell cycle G1/S transition. 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. Amplification or overexpression of cyclin D1 plays a pivotal role in the development of various human tumors including parathyroid adenoma, breast tumor, colon tumor, lymphoma, melanoma and prostate tumor. Cyclin D1 also associates with and regulates the activity of transcription factors, coactivators and corepressors that govern histone acetylation and chromatin remodeling proteins.
