Area of Science:

  • Biochemistry
  • Molecular Biology
  • Cellular Signaling

Background:

  • Lysophospholipids (LPs) elicit diverse cellular responses.
  • The molecular mechanisms underlying LP signaling were previously unknown due to the absence of identified LP receptors.

Purpose of the Study:

  • To review the features of the newly identified lysophospholipid receptor family.
  • To discuss the biological significance of receptor-mediated LP signaling.

Main Methods:

  • Cloning and functional identification of the first LP receptor, lp(A1)/vzg-1.
  • Classification of related orphan receptors as members of a G protein-coupled receptor family.
  • Review of molecular characteristics, genomics, signaling properties, and gene expression of LP receptors.
