The phosphatidylinositol 3‐phosphate‐binding FYVE finger [PDF]
FEBS Letters, 2002 The FYVE zinc finger domain is conserved from yeast (five proteins) to man (27 proteins). It functions in the membrane recruitment of cytosolic proteins by binding to phosphatidylinositol 3‐phosphate (PI3P), which is found mainly on endosomes. Here we review recent work that sheds light on the targeting of FYVE finger proteins to PI3P‐containing ...

Characterization of VPS34-IN1, a selective inhibitor of Vps34, reveals that the phosphatidylinositol 3-phosphate-binding SGK3 protein kinase is a downstream target of class III phosphoinositide 3-kinase [PDF]
, 2014 The Vps34 (vacuolar protein sorting 34) class III PI3K (phosphoinositide 3-kinase) phosphorylates PtdIns (phosphatidylinositol) at endosomal membranes to generate PtdIns(3)P that regulates membrane trafficking processes via its ability to recruit a ...

Nature Communications, 2023 Exosomes are secreted to the extracellular milieu when multivesicular endosomes (MVEs) dock and fuse with the plasma membrane. However, MVEs are also known to fuse with lysosomes for degradation.

Editorial: Membrane lipids in T cell functions [PDF]
, 2018 Plasma membrane lipids play essential roles in regulating T cell signaling, differentiation, and effector functions. The major lipid species in the plasma membrane are glycerophospholipids, sphingolipids, and sterol lipids.

Regulation of autophagy by phosphatidylinositol 3‐phosphate [PDF]
FEBS Letters, 2010 The simple phosphoinositide phosphatidylinositol 3‐phosphate (PI(3)P) has been known to have important functions in endocytic and phagocytic traffic, and to be required for the autophagic pathway. In all of these settings, PI(3)P appears to create platforms that serve to recruit specific effectors for membrane trafficking events.

Hepatology, EarlyView., 2022 Increased liver content of DHA‐derived small lipid autacoids (i.e resolvin D1 and maresin 1) associates with enhanced mitochondrial oxidative phosphorylation, fatty acid β‐oxidation and bioenergetic metabolic flux. These features provide hepatic protection from steatotic, pro‐inflammatory and fibrogenic insults.

Hepatology, EarlyView., 2022 CHIN117 is a dual cysteinyl leukotriene receptor 1 (CYSLTR1) antagonist and G‐protein‐coupled bile acid receptor 1 (GPBAR1) agonist. In the liver, GPBAR1 and CYSLTR1 are coexpressed by liver sinusoidal endothelial cells (LSECs), HSCs, circulating monocytes/macrophages, and liver resident macrophages (Kupffer cells).

Purification of polyphosphoinositides by chromatography on immobilized neomycin.
Journal of Lipid Research, 1978 The binding of polyphosphoinositides (phosphatidylinositol phosphate and phosphatidylinositol bisphosphate) to the antibiotic neomycin is utilized for the purification of these lipids.
