Error bars present the SD through the mean. activity and impairs development of actin areas, whereas expression of the phosphomimicking Src-S51D proteins rescues actin areas and stops chromatin damage in Chk1-lacking cells. We suggest that Chk1 Obatoclax mesylate (GX15-070) phosphorylates Src-S51 to totally stimulate Src kinase activity which phosphorylated Src Continue Reading
