A genetic interaction between the vesicular acetylcholine transporter VAChT/UNC-17 and synaptobrevin/SNB-1 in C. elegans

Acetylcholine, a major excitatory neurotransmitter in Caenorhabditis elegans, is transported into synaptic vesicles by the vesicular acetylcholine transporter encoded by unc-17. The abnormal behavior of unc-17(e245) mutants, which have a glycine-to-arginine substitution in a transmembrane domain, is markedly improved by a mutant synaptobrevin with an isoleucine-to-aspartate substitution in its transmembrane domain.
