General description

Phosphatidic acid (PA) is a precursor of lysophosphatidic acid (LPA) and is present in leafy vegetables. 18:2 PA or 1,2-dilinoleoyl-sn-glycero-3-phosphate (sodium salt) is a sodium salt of glycerol phosphate, with substitution of two chains of linolenic acid at the sn-1 and sn-2 positions in the glycerol backbone.

Application

18:2 PA or 1,2-dilinoleoyl-sn-glycero-3-phosphate (sodium salt):
  • has been used as a supplement in mouse chow to see changes in small intestine gene expression
  • might be used in saposin-derived lipid nanoparticle (SapNP) formation
  • might be used in vacuolar mimic lipid (VML) proteoliposomes used for content-mixing assays

Saposin-derived lipid nanoparticles (SapNPs) are a new alternative tool for membrane protein reconstitution. Here we demonstrate the potential and advantages of SapNPs. We show that SapA has the lowest lipid specificity for SapNP formation. These nanoparticles are modular and offer

We recently reported that levels of unsaturated lysophosphatidic acid (LPA) in the small intestine significantly correlated with the extent of aortic atherosclerosis in LDL receptor-null (LDLR⁻/⁻) mice fed a Western diet (WD). Here we demonstrate that WD increases unsaturated (but

Yeast vacuole fusion requires R-SNARE, Q-SNAREs, and HOPS. A HOPS SM-family subunit binds the R- and Qa-SNAREs. We now report that HOPS binds each of the four SNAREs. HOPS catalyzes fusion when the Q-SNAREs are not pre-assembled, ushering them into
