Anti-CDK6 Antibody (Monoclonal, DCS-90)

The cyclin-dependent protein kinases (CDKs) regulate major cell cycle transitions in eukaryotic cells. Cyclin-dependent kinase-6 (CDK6) is the earliest inducible member of the CDK family in human T lymphocytes, involved in growth factor stimulation and cell cycle progression. Germline mutations in CDK6 do not make a significant contribution to melanoma predisposition. CDK6 gene is mapped at 7q21-q22.

CDK6: Expressed ubiquitously. Accumulates insquamous cell carcinomas, proliferating hematopoietic progenitorcells, beta-cells of pancreatic islets of Langerhans, andneuroblastomas. Reduced levels in differentiating cells.

CDK6: Serine/threonine-protein kinase involved in the controlof the cell cycle and differentiation; promotes G1/S transition.Phosphorylates pRB/RB1 and NPM1. Interacts with D-type G1 cyclinsduring interphase at G1 to form a pRB/RB1 kinase and controls theentrance into the cell cycle. Involved in initiation andmaintenance of cell cycle exit during cell differentiation; prevents cell proliferation and regulates negatively celldifferentiation, but is required for the proliferation of specificcell types (e.g. erythroid and hematopoietic cells) . Essential forcell proliferation within the dentate gyrus of the hippocampus andthe subventricular zone of the lateral ventricles. Required duringthymocyte development. Promotes the production of newborn neurons, probably by modulating G1 length. Promotes, at least inastrocytes, changes in patterns of gene expression, changes in theactin cytoskeleton including loss of stress fibers, and enhancedmotility during cell differentiation. Prevents myeloiddifferentiation by interfering with RUNX1 and reducing itstranscription transactivation activity, but promotes proliferationof normal myeloid progenitors. Delays senescence. Promotes theproliferation of beta-cells in pancreatic islets of Langerhans.May play a role in the centrosome organization during the cellcycle phases (PubMed:23918663) .
