Enables transmitter-gated ion channel activity involved in regulation of postsynaptic membrane potential. Predicted to be involved in several processes, including cellular response to ethanol; cellular response to zinc ion; and chloride transmembrane transport. Located in glycinergic synapse. Is expressed in brain and spinal cord. Orthologous to human GLRA2 (glycine receptor alpha 2). [provided by Alliance of Genome Resources, Apr 2022]
