Enables G-protein alpha-subunit binding activity and phospholipid binding activity. Involved in positive regulation of calcium ion transport and positive regulation of cytosolic calcium ion concentration involved in phospholipase C-activating G protein-coupled signaling pathway. Predicted to be located in axon. Predicted to be active in cytoplasm and plasma membrane. Orthologous to human LPAR3 (lysophosphatidic acid receptor 3).
