Target Background

Receptor for lysophosphatidic acid (LPA), a mediator of diverse cellular activities. Transduces a signal by increasing the intracellular calcium ions and by stimulating adenylyl cyclase activity. The rank order of potency for agonists of this receptor is 1-oleoyl- > 1-stearoyl- > 1-palmitoyl- > 1-myristoyl- > 1-alkyl- > 1-alkenyl-LPA.
Gene References into Functions
  1. Mutation in LPAR4 gene is associated with papillary thyroid carcinoma. PMID: 26941397
  2. These results suggest that the diverse roles of LPA4, LPA5 and LPA6 are involved in the activation of tumor progression in pancreatic cancer cells. PMID: 25849892
  3. Our data suggest that LPA4 signaling potentially modulates malignant behavior of SQ-20B cells. PMID: 23467751
  4. LPA4 gene mutation may play some role in the pathogenesis of colon cancer. PMID: 20890765
  5. LPA4 and LPA5 receptors induce osteoblastic differentiation of human mesenchymal stem cells PMID: 20069565
  6. identified as the fourth lysophosphatidic acid (LPA) receptor; shares only 20-24% amino acid identities with Edg-2/LPA1, Edg-4/LPA2, and Edg-7/LPA3, and phylogenetic analysis also shows that p2y9/GPR23 is far distant from the Edg family PMID: 12724320
