Other interactions of PPAP2B

  • The pulmonary LPP1 and LPP3 isoforms are essentially identical to the previously cloned rat liver and intestinal LPPs, respectively, and the LPP1a isoform has 80% sequence identity to the human homolog [4].
  • Km values for each of the substrates, respectively, were (in microM) PAP-2a: 98, 170, 116; PAP-2b: 100, 110, 56; and PAP-2c: 150, 340, 138 [11].
  • The effects of hLPP-3 on colony-forming activity were substantially reversed by the LPP-resistant LPA analogue, O-methylphosphothionate [2].
 

Analytical, diagnostic and therapeutic context of PPAP2B

  • The RT-PCR generated LPP1 (849 bp), up to three LPP1 variants, and LPP3 (936 bp) cDNAs [4].
  • Strikingly, coculture of hLPP-3-expressing cells with nontransfected parental cells decreased the colony-forming activity of the parental cells, compatible with hLPP-3 decreasing levels of an extracellular mediator, likely LPA [2].
  • GST-mLpp3-RGE interacted with alpha(5)beta(1) and alpha(v)beta(3) integrins in a solid-phase ELISA, while a mutant control, GST-hLPP3-RAD, did not [12].
