Abstract:
:Recent studies have implicated that a GTP-binding protein (G-protein) is involved in the coupling of both CCK-8 and muscarinic cholinergic receptors to phosphoinositidase C (PIC) in the human embryonic pituitary cell line, Flow 9000. Pretreatment of these cells with cholera toxin, but not pertussis toxin, inhibited the stimulation of [3H]inositol phosphate production by CCK-8 and acetylcholine. These inhibitory effects of cholera toxin could not be reproduced by treating the cells with the B-subunit of cholera toxin or cAMP-generating agents such as forskolin. These data suggest the presence of a novel Gc protein which is responsible for receptor-PIC coupling in Flow 9000 cells.
