Abstract	In dinoflagellates, the formation of cysts can be induced by indoleamines, and such responses exhibit reversibility and agonist selectivity. The encystment responses in two species of dinoflagellates, Crypthecodinium cohnii and Gonyaulax tamarensis, were examined for the possible involvement of G proteins. An antiserum against conserved regions of the α subunits of mammalian G proteins detected several substrates in dinoflagellate membranes, suggesting the presence of G proteins in this group. In support of this finding, mastoparan, (a direct activator of mammalian G proteins) was able to induce encystment. The trypnitized peptide was ineffective, indicating that the mastoparan-induced encystment was specific to the structure of mastoparan. Both biochemical and pharmacologic evidence favor the idea that indoleamine-induced encystment in dinoflagellates may be mediated via the signal-transducting G proteins.
