Cargo recognition and trafficking in selective autophagy

TLDR: The current view on how cargo selection and transport are achieved during selective autophagy is discussed, and molecular mechanisms that are congruent between autophagosomal membranes and vesicle trafficking pathways are pointed out.

Abstract: Selective autophagy is a quality control pathway through which cellular components are sequestered into double-membrane vesicles and delivered to specific intracellular compartments. This process requires autophagy receptors that link cargo to growing autophagosomal membranes. Selective autophagy is also implicated in various membrane trafficking events. Here we discuss the current view on how cargo selection and transport are achieved during selective autophagy, and point out molecular mechanisms that are congruent between autophagy and vesicle trafficking pathways.
