General description

Lysophosphatidylinositol (LPI), an acidic lysophosholipid, carries inositol in its head group.

Application

18:0 Lyso PI (1-stearoyl-2-hydroxy-sn-glycero-3-phosphoinositol) has been used as lysophosphatidylinositol (LPI) substrate in lysophosphatidylinositol acyltransferase biochemical assay to determine lyso-phosphatidylinositol acyltransferase (LPIAT) activity of liver microsomes. It may be used as a synthetic LPI to compare its effects with liver LPI in transferrin (Tf) endocytosis. It may also be used as LPI standard to quantify serum LPI levels in gonadectomized rats.

Biochem/physiol Actions

Increased circulating levels of L-alpha-lysophosphatidylinositol (LPI) are associated with cancer and LPI is a potent ligand for the G-protein-coupled receptor GPR55.
Lysophosphatidylinositol (LPI) displays mitogenic activity and can serve as a bioactive lysophospholipid mediator. It may be considered as a lipid mediator.

GPR55 is an orphan G protein-coupled receptor. In this study, we explored a possible endogenous ligand for GPR55 using HEK293 cells which expressed GPR55. We found that lysophosphatidylinositol induced rapid phosphorylation of the extracellular signal-regulated kinase in transiently or stably
