Biogenesis and Cargo Selectivity of Autophagosomes
Abstract
Autophagy is a major catabolic pathway in eukaryotes, which is required for the lysosomal/vacuolar degradation of cytoplasmic proteins and organelles. Interest in the autophagy pathway has recently gained momentum largely owing to identification of multiple autophagy-related genes and recognition of its involvement in various physiological conditions. Here we review current knowledge of the molecular mechanisms regulating autophagy in mammals and yeast, specifically the biogenesis of autophagosomes and the selectivity of their cargo recruitment. We discuss the different steps of autophagy, from the signal transduction events that regulate it to the completion of this pathway by fusion with the lysosome/vacuole. We also review research on the origin of the autophagic membrane, the molecular mechanism of autophagosome formation, and the roles of two ubiquitin-like protein families and other structural elements that are essential for this process. Finally, we discuss the various modes of autophagy and highlight their functional relevance for selective degradation of specific cargos.

“Although autophagic cargo can be trapped passively within the autophagosome in nonselective autophagy, direct substrate recruitment to phagophores in selective autophagy is mediated by a series of receptor proteins (e.g., SQSTM1/p62 [sequestosome 1], NBR1, AMBRA1) that contain both an LC3-interacting region (LIR) and separate motifs for binding polyubiquitinated proteins [41].”

“Expansion then occurs through maturation of the extending phagophore membrane guided by the ATG12–ATG5-ATG16L1 complex, catalyzing insertion of MAP1LC3/LC3 (microtubule associated protein 1 light chain 3) into the phagophore membrane [40,41].”

In the citing paper
“Before membrane insertion, the unbound and immature LC3 precursor protein (LC3-I) undergoes proteolytic processing by ATG4, and conjugation to phosphatidylethanolamine through ATG7 and ATG3. The resulting mature, lipidated isoform (LC3-II) is incorporated into the phagophore membrane [41].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
