Phorbol 12-myristate 13-acetate (PMA), a phorbol ester, is a reversible, highly potent activator of protein kinase C (PKC), including Group A and Group B isoforms (Blumberg). PMA activates PKC isoforms through the binding of the C1 domain (Hurley et al.). PMA can also activate certain mitogen-activated protein (MAP) kinase pathways through PKC (Adams & Parker).
