PG - 181-4 AB - Lipid phosphate phosphatase-1 (LPP-1) dephosphorylates exogenous lysophosphatidate and thereby regulates the activation of lysophosphatidate receptors and cell division. Mutation of seven amino acids in three conserved domains of mouse LPP-1 abolished its activity. A glycosylation site was demonstrated between conserved Domains 1 and 2. LPP-1 is expressed in the plasma membrane, and the present results demonstrate the active site to be located on the outer surface.
