Summary: Enables PDZ domain binding activity. Acts upstream of or within G protein-coupled receptor signaling pathway; positive regulation of MAPK cascade; and positive regulation of Rho protein signal transduction. Is active in glutamatergic synapse and presynaptic active zone membrane. Is expressed in several structures, including alimentary system; branchial arch; central nervous system; hemolymphoid system gland; and sensory organ. Orthologous to human LPAR2 (lysophosphatidic acid receptor 2). [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.
