The function of Ensembl gene identifier ENSG00000101958 (GLRA2, glycine receptor alpha 2) is as follows. Subunit of heteromeric glycine-gated chloride channels (PubMed:15302677, PubMed:16144831, PubMed:2155780, PubMed:23895467, PubMed:25445488, PubMed:26370147, PubMed:34473954). Plays a role in synaptic plasticity (By similarity). Contributes to the generation of inhibitory postsynaptic currents, and is involved in the down- regulation of neuronal excitability (PubMed:25445488). Plays a role in cellular responses to ethanol (PubMed:23895467). {ECO:0000250|UniProtKB:Q7TNC8, ECO:0000269|PubMed:15302677, ECO:0000269|PubMed:16144831, ECO:0000269|PubMed:2155780, ECO:0000269|PubMed:23895467, ECO:0000269|PubMed:25445488, ECO:0000269|PubMed:34473954}.
