Although molecular biology provides new insights into the subunit compositions and the stoichiometries of insect neuronal nicotinic acetylcholine receptors (nAChRs), our knowledge about the phosphorylation/dephosphorylation mechanisms of native neuronal nAChRs is limited. The regulation of a-bungarotoxin-resistant nAChRs was studied on dissociated adult dorsal unpaired median neurons isolated f...
