LAMP proteins, the major glycoproteins of the lysosome membrane, bind cholesterol directly and specifically, and interact with NPC1 and NPC2 proteins as part of the lysosomal cholesterol export process.
A post-lysosomal cholesterol transport inhibitor reveals how the endoplasmic reticulum membrane regulates total cellular cholesterol by constantly monitoring a critical pool of cholesterol in the plasma membrane.
Identification of a transporter complex comprised of SLC37A3 and ATRAID is required for nitrogen-containing bisphosphonates to enter the cytosol from lysosomes and exert their therapeutic effects on bone.
The signaling lipid PI(3,5)P2 supports the formation of the myelin sheath, by regulating trafficking of myelin building blocks within oligodendrocytes and communication between oligodendrocytes and neuronal axons.
Analyses of a developmentally regulated Drosophila myofiber remodeling program provide insight into induced autophagy required for T-tubule membrane reorganization, and uncover a conserved Rab2 role in autophagosome-lysosome fusion.
