Long-Lived Protein Degradation During Autophagy

Methods Enzymol. 2017:588:31-40. doi: 10.1016/bs.mie.2016.09.074. Epub 2016 Nov 11.

Abstract

Macroautophagy, a major lysosomal degradative pathway for cytoplasmic components, is a process that can be stimulated in response to many stressful situations including cancer treatment. The central autophagic organelle is the autophagosome, a double-membrane-bound vacuole that sequesters cytoplasmic material. The ultimate destiny of the autophagosome is fusion with the lysosomal compartment, where cargo, including proteins, is degraded. Here, we report a method to measure the lysosomal degradation of long-lived proteins along the autophagic pathway.
