Post Translational Modifications
Phosphorylation at Thr-286 by MAP kinases is required for ubiquitination and degradation by the DCX(AMBRA1) complex. It also plays an essential role for recognition by the FBXO31 component of SCF (SKP1-cullin-F-box) protein ligase complex following DNA damage. Ubiquitinated at Lys-269 by the DCX(AMBRA1) complex during the transition from G1 to S cell phase, leading to its degradation: ubiquitination is dependent on Thr-286 phosphorylation. The DCX(AMBRA1) complex represents the major regulator of CCND1 stability during the G1/S transition. Also ubiquitinated by the SCF(FBXO4) and Cul7-RING(FBXW8) ubiquitin-protein ligase complexes. Following DNA damage it is ubiquitinated by the SCF(FBXO31) protein ligase complex. SCF(FBXO31) ubiquitination is dependent on Thr-286 phosphorylation. Ubiquitinated also by UHRF2 apparently in a phosphorylation-independent manner. Ubiquitination leads to its degradation and G1 arrest. Deubiquitinated by USP2.leading to its stabilization.
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 a 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.
