GTP-binding protein (G protein) linking to metabotropic glutamate receptor of bovine retinal on-bipolar cell was studied by use of pharmacologically selective ligands, 2-amino-4-phosphonobutyric acid (APB) on bacterial toxin-catalyzed ADP-ribosylation and GTP gamma S-binding. In contrast to the electrophysiological findings reported, G protein coupling to… (More)

The transduction in photoreceptors and chemoreceptors has common mechanisms. In photoreceptors, activation of rhodopsin by light triggers the enzymatic cascade mediated by a G-protein, transducin. In olfactory cells activation of the receptor molecule by odorant triggers the enzymatic cascade mediated by a G-protein, Golf. In taste receptor cells… (More)
