Ubiquitination of ERMES components by the E3 ligase Rsp5 is involved in mitophagy
Mitochondria are dynamic organelles that undergo permanent fission and fusion events. These processes play an essential role in maintaining normal cellular function. In the yeast Saccharomyces cerevisiae, the endoplasmic reticulum-mitochondrial encounter structure (ERMES) is a marker of sites of mitochondrial division, but it is also involved in a plethora of other mitochondrial functions. Howe...
متن کاملPhospholipid transfer proteins revisited.
Phosphatidylinositol transfer protein (PI-TP) and the non-specific lipid transfer protein (nsL-TP) (identical with sterol carrier protein 2) belong to the large and diverse family of intracellular lipid-binding proteins. Although these two proteins may express a comparable phospholipid transfer activity in vitro, recent studies in yeast and mammalian cells have indicated that they serve complet...
متن کاملPhospholipid transfer protein and atherosclerosis.
Genetic studies in humans and mice show that two related plasma lipid transfer proteins (cholesteryl ester transfer protein [CETP] and phospholipid transfer protein [PLTP]) have distinct roles in lipoprotein metabolism, despite their homology.1 In human homozygous CETP deficiency, HDL levels are massively elevated, and LDL levels are moderately decreased.2 While a human PLTP deficiency state ha...
متن کاملHeme transfer between phospholipid membranes and uptake by apohemoglobin.
The incorporation of CO-heme into single bilayer, egg lecithin vesicles was examined by following the spectral changes that occur when the porphyrin becomes embedded in the membranes. The rate of CO-heme uptake by liposomes is extremely fast (t1/2 less than or equal to 20 ms at 10 degrees C), and the maximum extent is roughly 1 heme/5 phospholipid molecules. This limiting stoichiometry is due t...
متن کاملNO2 interfacial transfer is reduced by phospholipid monolayers.
Nitrogen dioxide (NO2) is a ubiquitous, pollutant gas that produces a broad range of pathological and physiological effects on the lung. Absorption of inhaled NO2 is coupled to near-interfacial reactions between the solute gas and constituents of the airway and alveolar epithelial lining fluid. Although alveolar surfactant imparts limited resistance to respiratory gas exchange compared with tha...
