Lysophosphatidic acid receptor 3 also known as LPA₃ is a protein that in humans is encoded by the LPAR3 gene.^[1]^[2] LPA₃ is a G protein-coupled receptor that binds the lipid signaling molecule lysophosphatidic acid (LPA).^[3]

Function

This gene encodes a member of the G protein-coupled receptor family, as well as the EDG family of proteins. This protein functions as a cellular receptor for lysophosphatidic acid and mediates lysophosphatidic acid-evoked calcium mobilization. This receptor couples predominantly to G(q/11) alpha proteins.^[1]
