Phosphorylation of RB1 allows dissociation of the transcription factor E2F from the RB\/E2F complexes 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 phosphorylates SMAD3 in a cell-cycle-dependent manner and represses its transcriptional activity. Component of the ternary complex, cyclin D\/CDK4\/CDKN1B, required for nuclear translocation and activity of the cyclin D-CDK4 complex (By similarity). .\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eScientific background (datasheet):\u003c\/strong\u003e Cyclin-dependent kinase-4 (CDK4) is a protein-serine kinase involved in the cell cycle. Human cell division is regulated primarily at the G1-to-S or the G2-to-M boundaries within the cell cycle. The complexes formed by CDK4 and the D-type cyclins are involved in the control of cell proliferation during the G1 phase. CDK4 is inhibited by p16, also known as cyclin-dependent kinase inhibitor-2. CDK4 is mapped to 12q14. CDK4 expression and activity are required for cytokine responsiveness in T cells.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCellular localization (datasheet):\u003c\/strong\u003e Cytoplasm . Nucleus . Membrane . Cytoplasmic when non- complexed. Forms a cyclin D-CDK4 complex in the cytoplasm as cells progress through G (1) phase. The complex accumulates on the nuclear membrane and enters the nucleus on transition from G (1) to S phase. Also present in nucleoli and heterochromatin lumps. Colocalizes with RB1 after release into the nucleus (By similarity). .\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTissue details (datasheet):\u003c\/strong\u003e Expressed (at protein level) in a wide range of tissues with highest levels in brain, spinal cord, testis, pancreas, heart, spleen and mammary glands.
