Anti-CDK4 Antibody

Description

The protein encoded by this gene is a member of the Ser/Thr protein kinase family. This protein is highly similar to the gene products of S. cerevisiae cdc28 and S. pombe cdc2. It is a catalytic subunit of the protein kinase complex that is important for cell cycle G1 phase progression. The activity of this kinase is restricted to the G1-S phase, which is controlled by the regulatory subunits D-type cyclins and CDK inhibitor p16 INK4a . This kinase was shown to be responsible for the phosphorylation of retinoblastoma gene product Rb . Mutations in this gene as well as in its related proteins including D-type cyclins, p16 INK4a and Rb were all found to be associated with tumorigenesis of a variety of cancers. Multiple polyadenylation sites of this gene have been reported. provided by RefSeq, Jul 2008
