A role for chloride transport in lysosomal protein degradation.

abstract：:Macroautophagy/autophagy involves the formation of an autophagosome, a double-membrane vesicle that delivers sequestered cytoplasmic cargo to lysosomes for degradation and recycling. Closely related, endocytosis mediates the sorting and transport of cargo throughout the cell, and both processes are important for cellu...
