The redistribution of protein kinase C (PKC) isoforms between the cytosolic and plasma membrane fractions of stimulated human polymorphonuclear leukocytes (PMN) was analysed by means of western blotting with antibodies against PKC beta I, beta II and Zeta. Treatment of PMN with 1 microM formyl-methionyl-leucyl-phenylalanine (fMLP) induced a rapid (5-10 sec) and sustained (at least 10 min) increase in the membrane association of PKC beta I, beta II, and the two immunoreactive proteins (76-81 kDa) recognized by the antibody directed against PKC zeta. Optimal translocation of PKC isoforms to the plasma membrane occurred in the presence of 10(-6) M fMLP and was not associated with a detectable fall in cytosolic PKC. In the absence of external calcium, the translocation of all PKC isoforms induced by fMLP was rapid (5 sec) but the membrane association of PKC was lost within one minute. Unlike fMLP, phorbol myristate acetate (PMA) induced a concentration-dependent translocation of the PKC isoforms, which persisted in the membrane in the absence of external calcium. These data provide the first evidence of redistribution of PKC isoforms by a chemoattractant. They further indicate that external calcium plays a crucial role in the persistence of the membrane association of PKC beta I, beta II and zeta induced by formyl peptides.
