LPAR2

A gene on chromosome 19p12 that encodes an endothelial differentiation, G protein-coupled (EDG) family receptor for lysophosphatidic acid (LPA), a bioactive lysophospholipid that mediates diverse biologic functions, including proliferation, platelet aggregation, smooth
muscle contraction, inhibition of neuroblastoma cell differentiation, chemotaxis and tumour cell invasion. LPAR2 contributes to Ca2+ mobilisation, a critical cellular response to LPA in cells, by association with Gi and Gq proteins.

This signaling pathway involves lysophosphatidic acid (LPA) acting via presynaptic LPA2 receptors.
To investigate how LPA exerted this effect, the team produced mice that genetically lack one or both of the two receptors -- LPA1 and LPA2 -- to which LPA can bind on ventricle-building fetal progenitor cells, finding that the LPA1 receptor was required to produce hydrocephalus.
69) The G protein-coupled receptors for lysophosphatidic acid, LPA1 and LPA2, which can signal through nuclear factor [kappa]B or Akt, were recently shown by Yamada et al (70) to be expressed in MPM cell lines and human samples, and the addition of LPA enhanced cell proliferation and motility via LPA1 and LPA2, respectively.
Although LPA2 shares a high degree of sequence homology with LPA3, DGPP is not an antagonist for LPA2.
Site-directed mutagenesis was performed on LPA2 and LPA3 to mutate residues predicted to be critical for binding to DGPP.
