Purity: > 95% by SDS - PAGE Format: Liquid in 20mM Tris pH7.5, 20% Glycerol. CKS2, also known as CDC28 Protein kinase 2 associates with the catalytic subunit of cyclin-dependent kinases and has therefore been assumed to play a direct role in cell cycle regulation. The function of CKS2 in somatic mammalian cells is not well understood although it is required for the first metaphase/anaphase transition during the meiosis. Emerging evidence shows that elevated expression of CKS2 protects the cells from apoptosis. Recombinant CKS2 fused with T7-tag was expressed in E.coli and purified by conventional chromatography techniques.
