Web8 mar. 2024 · The dynamic process of lysosome-mitochondria contact sites is in a balance between contact tethering and untethering, which can be regulated by various proteins associated with lysosomal and mitochondrial membranes (Cisneros et al. 2024 ), as well as lysosomal Ca 2+ release (Peng et al. 2024 ). WebER-endosome contact sites take part in various molecular functions, including lipid trafficking, growth factor signaling, organelle fission, kinesin and dynein motor lysosomal transport and endosomal positioning. 1, 2, 18, 22, 33. One of the ways by which ER-lysosome contact sites control directionality of transport involves the lipid cholesterol.
