ER membranes exhibit phase behavior at sites of organelle contact
Significance Membrane phase behavior in cells permits transient concentration of specific proteins and lipids into dynamic nanoscopic domains. Here, we tested the existence and role of such phase behavior in endoplasmic reticulum (ER) membranes ...

Repeat Expansions in PLIN4 Cause Autosomal Dominant Vacuolar Myopathy With Sarcolemmal Features
ABSTRACT Objective We aim to describe and characterize two unrelated Spanish families suffering from an autosomal dominant autophagic vacuolar myopathy caused by repeat expansions in PLIN4. Methods We evaluated the clinical phenotype and muscle imaging, and performed a genetic workup that included exome sequencing, muscle RNAseq, and long‐read genome ...

Outer envelope membranes from chloroplasts are isolated as right-side-out vesicles [PDF]
Outer envelope membranes were isolated from purified chloroplasts of pea leaves. The sidedness of the vesicles was analyzed by (i) aqueous polymer-two phase partitioning, (ii) the effect of limited proteolysis on the outer-envelope proteins (OEP) 86 and ...

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Syntaphilin Ubiquitination Regulates Mitochondrial Dynamics and Tumor Cell Movements. [PDF]
Syntaphilin (SNPH) inhibits the movement of mitochondria in tumor cells, preventing their accumulation at the cortical cytoskeleton and limiting the bioenergetics of cell motility and invasion. Although this may suppress metastasis, the regulation of the

Changes in membrane lipids drive increased endocytosis following Fas ligation [PDF]
Once activated, some surface receptors promote membrane movements that open new portals of endocytosis, in part to facilitate the internalization of their activated complexes.
