Disease:A chromosomal aberration involving CCND1 may be a cause of B-lymphocytic malignancy , particularly mantle-cell lymphoma (MCL) . Translocation t (11;14) (q13;q32) with immunoglobulin gene regions. Activation of CCND1 may be oncogenic by directly altering progression through the cell cycle. ,Disease:A chromosomal aberration involving CCND1 may be a cause of multiple myeloma [MIM:254500]. Translocation t (11;14) (q13;q32) with the IgH locus. ,Disease:A chromosomal aberration involving CCND1 may be a cause of parathyroid adenomas [MIM:168461]. Translocation t (11;11) (q13;p15) with the parathyroid hormone (PTH) enhancer. ,Function:Essential for the control of the cell cycle at the G1/S (start) transition. ,online information:The Singapore human mutation and polymorphism database ,PTM:Following DNA damage it is ubiquitinated by some SCF (SKP1-cullin-F-box) protein ligase complex containing FBXO31. Ubiquitination leads to its degradation and G1 arrest. ,PTM:Phosphorylation at Thr-286 by MAP kinases is required for ubiquitination and degradation following DNA damage. It probably plays an essential role for recognition by the FBXO31 component of SCF (SKP1-cullin-F-box) protein ligase complex. ,similarity:Belongs to the cyclin family. ,similarity:Belongs to the cyclin family. Cyclin D subfamily. ,subunit:Interacts with the CDK4 and CDK6 protein kinases to form a serine/threonine kinase holoenzyme complex. The cyclin subunit imparts substrate specificity to the complex. ,
