Cyclin-Dependent Kinase 4 (CDK4) is a member of the Ser/Thr protein kinase family. It functions as the catalytic subunit of the cyclin D-CDK4 (DC) complex that is important for cell cycle progression through the G1 phase. The DC complexes accumulate on the nuclear membrane and are transported to the nucleus when cells enter S phase. In the nucleus, DC complexes phosphorylate and inhibit the retinoblastoma (Rb) proteins. Phosphorylation of Rb protein results in dissociation of the transcription factor E2F from the Rb/E2F complex and activation of E2F target genes. This process is controlled by D-type cyclins and CDK inhibitor p16 (CDK4I). Formation of the ternary complex, cyclin D/CDK4/CDKN1B, is required for nuclear translocation and DC complex activity. Mutations of CDK4 gene have been found to be associated with the tumorigenesis of many cancers such as cutaneous malignant melanoma.Product Details
