arachidonic acid appeared to interfere with the functions of both guanine nucleotide-binding stimulatory ( gs ) protein and the catalytic subunit of adenylate cyclase , since exogenously added arachidonic acid significantly suppressed the gtpase activity of p388d1 membrane and the forskolin response of the adenylate cyclase activity of gs protein deficient cyc- membrane .
