24212673-5	2013	Mutating snf-3 in a sensitized background caused the worms to be hypercontracted and paralyzed, presumably as a result of excess extracellular betaine.	Betaine	143-150	Sodium- and chloride-dependent betaine transporter	Caenorhabditis elegans	9-14	
24212673-6	2013	These behavioral defects were suppressed by mutations in acr-23, which encodes a ligand-gated cation channel of the cys-loop family.	Cysteine	116-119	Betaine receptor acr-23	Caenorhabditis elegans	57-63	
24212673-7	2013	ACR-23 was activated by betaine and functioned in the mechanosensory neurons to maintain basal levels of locomotion.	Betaine	24-31	Betaine receptor acr-23	Caenorhabditis elegans	0-6
