== Disease ==
[https://www.uniprot.org/uniprot/CDK4_HUMAN CDK4_HUMAN] Defects in CDK4 are a cause of susceptibility to cutaneous malignant melanoma type 3 (CMM3) [MIM:[https://omim.org/entry/609048 609048]. Malignant melanoma is a malignant neoplasm of melanocytes, arising de novo or from a pre-existing benign nevus, which occurs most often in the skin but also may involve other sites.<ref>PMID:7652577</ref> <ref>PMID:8528263</ref> <ref>PMID:9311594</ref> <ref>PMID:9425228</ref> 
== Function ==
[https://www.uniprot.org/uniprot/CDK4_HUMAN CDK4_HUMAN] Ser/Thr-kinase component of cyclin D-CDK4 (DC) complexes that phosphorylate and inhibit members of the retinoblastoma (RB) protein family including RB1 and regulate the cell-cycle during G(1)/S transition. 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.<ref>PMID:9003781</ref> <ref>PMID:15241418</ref> <ref>PMID:18827403</ref>
