Summary: Enables G-protein alpha-subunit binding activity and phospholipid binding activity. Involved in several processes, including cellular response to 1-oleoyl-sn-glycerol 3-phosphate; nervous system development; and regulation of vesicle-mediated transport. Located in dendritic shaft; dendritic spine; and neuronal cell body. Is active in GABA-ergic synapse; glutamatergic synapse; and synaptic membrane. Used to study hepatocellular carcinoma and transient cerebral ischemia. Orthologous to human LPAR1 (lysophosphatidic acid receptor 1). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
