Predicted to enable G protein-coupled receptor activity. Predicted to be involved in G protein-coupled receptor signaling pathway. Predicted to be located in membrane. Is an ortholog of C. elegans gar-3. In C. elegans, gar-3 is involved in several processes, including G protein-coupled acetylcholine receptor signaling pathway; positive regulation of acetylcholine secretion, neurotransmission; and positive regulation of protein localization to synapse.
