Target Information

Autophagy is a process of intracellular bulk degradation in which cytoplasmic components, including organelles, are sequestered within double-membrane vesicles that deliver the contents to the lysosome/vacuole for degradation. During macroautophagy, the sequestering vesicles, termed autophagosomes, fuse with the lysosome or vacuole resulting in the delivery of an inner vesicle (autophagic body) into the lumen of the degradative compartment.

There are 16 proteins participating in the autophagy pathway in humans. The autophagy protein LC3, a mammalian homologue of Atg8, was originally identified as microtubule-associated protein 1 light chain 3. LC3 is a component of both the MAP1A and MAP1B microtubule-binding domains, and its expression may regulate MAP1 microtubule-binding activity during development. LC3 is the only known mammalian protein that stably associates with autophagosome membranes. LC3-I is cytosolic, while LC3-II is membrane-bound and enriched in the autophagic vacuole fraction. Detection of LC3-I to LC3-II conversion is a sensitive marker for distinguishing autophagy in mammalian cells.
