Delivery of proteins and organelles to the vacuole from the cytoplasm

Curr Opin Cell Biol. 1998 Aug;10(4):523-9. doi: 10.1016/s0955-0674(98)80068-9.

Abstract

The vacuole/lysosome is a primary catabolic site in the eukaryotic cell. One implication of its cellular role is that delivery systems must exist to target both hydrolytic enzymes and substrates destined for degradation to this organelle. A number of nonclassical vacuolar targeting pathways that deliver degradative substrates and at least one resident enzyme from the cytosol to the vacuole have recently been described. The pathways identified so far include cytoplasm to vacuole targeting, macroautophagy, pexophagy and vacuolar import and degradation. Cytological, genetic and molecular genetic approaches have begun to provide insight into the molecular basis of these processes.
