Mark3 Lysates

MARK3 is a dual-specificity protein kinase that controls entry into mitosis by dephosphorylating Cdc2 on both threonine 14 and tyrosine 15. MARK3 is phosphorylated on serine 216 throughout interphase but not during mitosis. Serine 216 phosphorylation mediates the binding of 14-3-3 protein to MARK3, and MARK3/14-3-3 complexes are present throughout interphase but not during mitosis (1). Kinase suppressor of Ras (KSR) is a conserved component of the Ras pathway that interacts directly with MEK ...
