Research Abstract

Macroautophagy (autophagy) is a bulk protein-degradation system ubiquitously conserved in eukaryotic cells. During autophagy, cytoplasmic components are enclosed in a membrane compartment, called an autophagosome. In this study, we developed a method for monitoring intact autophagosomes ex vivo by detecting the fluorescence of GFP-fused aminopeptidase I, the best-characterized selective cargo of autophagosomes in Saccharomyces cerevisiae. A combination of LC-MS/MS with subsequent statistical analyses revealed a list of autophagosome cargo proteins. The methods we describe will be useful for analyzing the mechanisms and physiological significance of Atg11-independent selective autophagy.
