The ELISA kits listed below target CDK4, the symbol for the human gene, cyclin dependent kinase 4, and a member of the Protein kinase superfamily, CMGC Ser/Thr protein kinase family, CDC2/CDKX subfamily. The protein has an enzyme classification of cyclin-dependent kinase. The protein encoded by CDK4 has a predicted amino acid length of 303, a mass of 33.7 kDa, and a cytoplasmic and nuclear subcellular localization. There are currently 2 reported isoforms. Pathologic involvement is reported in Melanoma, cutaneous malignant 3. CDK4 may also be known by the following names: PSK-J3, CMM3, and cell division protein kinase 4. Orthologs of the gene, including human, mouse, rat, bovine, chicken, primate, guinea pig, fish, plant, and other mammalian are available targets of several ELISA kits.
