Lpar2 - lysophosphatidic acid receptor 2

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. Located in glutamatergic synapse. Is integral component of 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, Apr 2022]
