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. Source: Recombinant protein corresponding to aa1-79 of human CKS2 fused to T7-tag expressed in E. coli.
