The function of Ric-3, which is required for nicotinic acetylcholine receptor (nAChR) expression in C. elegans, is unclear. Here we found that Ric-3 can promote or inhibit cell-surface delivery of alpha-bungarotoxin-binding nAChRs (BgtRs) composed of alpha7 subunits. At low levels, Ric-3 promoted BgtR assembly, endoplasmic reticulum (ER) release, and(More)
The nicotinic acetylcholine receptor (nAChR) belongs to a family of five channel-forming proteins that regulate communication between the approximately 10(12) cells of the nervous system. A minimum mechanism of inhibition of the muscle-type nAChR (1) by the noncompetitive inhibitors cocaine and MK-801 [(+)-dizocilpine, an anticonvulsant] indicated they bind(More)
A mechanism for the alleviation of the malfunction of a mutated (gamma2(K289M)) epilepsy-linked gamma-aminobutyric acid (GABA) neurotransmitter receptor by phenobarbital is presented. Compared to the wild-type receptor, the GABA-induced current is considerably reduced in the mutated (alpha1beta2gamma2(K289M)) epilepsy-linked GABA(A) receptor [Baulac, S.,(More)
Although the antiepileptic properties of α-substituted lactams, acetamides, and cyclic imides have been known for over 60 years, the mechanism by which they act remains unclear. I report here that these compounds bind to the nicotinic acetylcholine receptor (nAChR) and inhibit its function. Using transient kinetic measurements with functionally active,(More)
