Abstract

The vacuole/lysosome performs a central role in degradation. Proteins and organelles are transported to the vacuole by selective and non-selective pathways. Transport to the vacuole by autophagy is the primary mode for degradation of cytoplasmic constituents under starvation conditions. Autophagy overlaps mechanistically and genetically with a biosynthetic pathway termed Cvt (Cytoplasm-to-vacuole targeting) that operates under vegetative conditions to transport the resident vacuolar hydrolase aminopeptidase I (API). API import has been dissected to reveal the action of a novel mechanism that transports cargo within double-membrane vesicles. Recent work has uncovered molecular components involved in autophagy and the Cvt pathway.
