Ionomycin 210-219 stathmin 1 Homo sapiens 95-99 7925472-8 1994 The CaM kinase-Gr is only expressed in certain lymphoid cell lines, and the present study shows that ionomycin-induced phosphorylation of Op18 Ser16 is restricted to cells expressing this protein kinase. Ionomycin 101-110 stathmin 1 Homo sapiens 138-142 8245003-6 1993 We also demonstrate that Ser-16 of Op18 is specifically phosphorylated in response to the Ca2+ signal generated by CD3 stimulation or by the Ca2+ ionophore ionomycin. Ionomycin 156-165 stathmin 1 Homo sapiens 35-39
