Purity: > 95% by SDS - PAGE Format: Liquid. In 20mM Tris-HCl buffer (pH 8.0) containing 2mM DTT, 10% glycerol, 200mM NaCl. CDKN2C (Cyclin-dependent kinase 4 inhibitor C ) belongs to the CDKN2 cyclin-dependent kinase inhibitor family. It has been shown to interact with CDK4 or CDK6, and prevent the activation of the CDK kinases, thus function as a cell growth regulator that controls cell cycle G1 progression. And this protein suppresses the cell growth and proliferation with a correlated dependence on endogenous retinoblastoma protein RB. Studies in the knockout mice suggested the roles of this gene in regulating spermatogenesis, as well as in suppressing tumorigenesis. Recombinant human CDKN2C protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.
