Data Examples
Detection of Human LPAR2 by Western Blot. Western blot shows lysates of human peripheral blood lymphocytes (PBL). PVDF Membrane was probed with 1 µg/mL of Human LPAR2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6396) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for LPAR2 at approximately 39 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Background: LPAR2/LPA2/EDG-4

LPAR2 (Lysophosphatidic acid receptor 2; also LPA2 and EDG4) is a 39 kDa member of the GPCR1 family of proteins.  It has limited expression, and is found on mammalian macrophages, fibroblasts and cardiac myocytes.  LPAR2 binds to, and is activated by LPA, a molecule principally derived from activated platelets.  Although LPAR2 appears to prefer myristoyl and palmitoyl LPA, multiple forms of LPA are recognized by the receptor.  LPAR2 reportedly mediates chemotaxis, arachidonic acid release, and cell rounding.  Human LPAR2 is a 351 amino acid (aa) 7–transmembrane (TM) protein (SwissProt # Q9HBW0).  It contains a 33 aa extracellular N-terminus (aa #1-33), seven TM segments (aa #34-297) and a 54 aa C-terminal cytoplasmic tail.  There is one splice variant that is associated with tumor cells, and which originally was given the designation EDG4 (endothelium differentiation gene 4).  This shows a 35 aa substitution for aa #348-351.  Over aa #1-33, 91-103, 168-188 and 264-279 collectively, human LPAR2 shares 75% aa identity with mouse LPAR2.
