a study of the changes in the lipid-soluble phosphatidyl inositol phosphates demonstrated that cyclic amp also stimulated a rapid loss of radioactivity from 32p-labelled phosphatidylinositol 4,5-bisphosphate ( ptdins ( 4,5 ) p2 ) , which corresponded in its timing to the rise in ins ( 1,4,5 ) p3 , indicating that a phosphoinositidase c ( phospholipase c ) is present that can be stimulated by occupation of the cell surface cyclic amp receptors .
