jca is not affected by treatment of synaptosomes with the adenylate cyclase activator forskolin , the membrane permeant dibutyryl-cyclic amp , or the kinase c activator phorbol 12-myristate 13-acetate diester , results suggesting that calcium channels in synaptosomes are not directly modulated by protein kinase a- or c-mediated phosphorylation .
