Detection of LPAR4 in HEK293 Human Cell Line Transfected with Human LPAR4 and eGFP by Flow Cytometry. HEK293 human embryonic kidney cell line transfected with (A) Human LPAR4 or (B) irrelevant protein, and EGFP, was stained with Mouse Anti-Human PE-conjugated LPAR4 Monoclonal Antibody (Catalog # FAB10217P). Quadrant markers were set based on Mouse IgG2B isotype control antibody staining (Catalog # IC0041P). View our protocol for Staining Membrane-associated Proteins.

Background: LPAR4/LPA4

Lysophosphatidic acid receptor 4, also known as LPA4, P2Y purinoceptor 9 (P2RY9) or GPR23, is a protein that in humans is encoded by the LPAR4 gene. LPA4 is a G protein-coupled receptor (GPCR) that binds the lipid signaling molecule lysophosphatidic acid (LPA) and mediates diverse cellular activities. Most LPA receptors share similarities with members of the S1P1/Edg family. GPA4, originally named P2Y9/GPR23, has been described as a fourth LPA receptor, LPA4, that together with LPA5 and LPA6 form a subfamily of LPA receptors structurally distant from the Edg family.
