    SUBCELLULAR LOCALIZATION     plasma membrane
    basic FUNCTION
  • hydrolyzes phospholipids and produces 2-acyl-lysophospholipids and fatty acids (Aoki 2007)
  • catalyzing the production of 2-acyl lysophosphatidic acid (LPA), lipid mediator with diverse biological properties including platelet aggregation, smooth muscle contraction, and stimulation of cell proliferation and motility
  • may be regulating hair growth
  • lipid mediator with wide variety of biological properties including stimulation of cell proliferation, migration, survival, wound healing in skin, cell clustering
  • have a role in the production of lysophosphatidylserine and lysophosphatidic acid mediators (Aoki 2007)
  • membrane-associated phosphatidic acid-preferring phospholipase A(1)alpha, and p.Cys246Ser- and p.His248Asn-LIPH mutants showed complete abolition of hydrolytic activity and had no LPAR6 activation ability, leading to pathogenesis of wolly hair or hypotrichosis
