the ability of anti-igm antibodies to activate phospholipase c in permeabilized wehi-231 cells was greatly increased by nonhydrolyzable guanosine 5'-triphosphate ( gtp ) analogues ( guanosine-5'-o- ( 3-thiotriphosphate ) or 5'-guanylylimidodiphosphate ) , but not by guanosine diphosphate or guanosine diphosphate analogues or by a nonhydrolyzable analogue of adenosine triphosphate .
