Predicted to enable glycine-gated chloride ion channel activity. Predicted to contribute to extracellularly glycine-gated chloride channel activity and glycine binding activity. Involved in regulation of synaptic vesicle exocytosis. Acts upstream of or within glutamate receptor clustering. Located in GABA-ergic synapse and glutamatergic synapse. Is active in glycinergic synapse. Is expressed in central nervous system and eye. Orthologous to human GLRA3 (glycine receptor alpha 3). [provided by Alliance of Genome Resources, Apr 2022]
