Abstract

The formation of autophagosomes and their fusion with lysosomes are key events that underpin autophagic degradation of cargoes. The core ATG8 system, which consists of the ATG8 family of ubiquitin-like proteins and the machineries that conjugate them onto autophagosomal membranes, are among the most-studied autophagy components. Despite the research focus on the core ATG8 system, there are conflicting reports regarding its essential roles in autophagy. Here, we reconcile prior observations of the core ATG8 system into a unifying model of their function that aims to consider apparently conflicting discoveries. Bypass pathways of autophagy that function independently of the core ATG8 system are also discussed.
