The lipid flippase Drs2 regulates anterograde transport of Atg9 during autophagy
Macroautophagy/autophagy is a conserved catabolic pathway during which cellular material is sequestered within newly formed double-membrane vesicles called autophagosomes and delivered to the lytic compartment of eukaryotic cells for degradation ...

Membrane remodeling by the PX-BAR protein SNX18 promotes autophagosome formation [PDF]
The membrane remodeling events required for autophagosome biogenesis are still poorly understood. Because PX domain proteins mediate membrane remodeling and trafficking, we conducted an imaging-based siRNA screen for autophagosome formation targeting ...

Toward a standard model for autophagosome biogenesis [PDF]
Two papers in this issue resolve a long-standing obstacle to a "standard model" for autophagosome biogenesis in mammals. The first, Olivas et al. (2023. J. Cell Biol.

Autophagosome formation machinery.
(1) The initiation of autophagosome formation requires the activation of the ULK complex (composed of ULK1/2 (unc-51-like kinases 1 and 2), ATG13, ATG101, and FIP200 (also known as RB1CC1)), which further activates ATG13 inducing its translocation to the

The Impact of Aging on Macroautophagy in the Pre-ovulatory Mouse Oocyte
Accompanying the precipitous age-related decline in human female fertility is an increase in the proportion of poor-quality oocytes within the ovary. The macroautophagy pathway, an essential protein degradation mechanism responsible for maintaining cell ...

The Intriguing Life of Autophagosomes [PDF]
Autophagosomes are double-membrane vesicles characteristic of macroautophagy, a degradative pathway for cytoplasmic material and organelles terminating in the lysosomal or vacuole compartment for mammals and yeast, respectively. This highly dynamic, multi-step process requires significant membrane reorganization events at different stages of the ...

Scaffolding the expansion of autophagosomes [PDF]
The conjugation of the small ubiquitin (Ub)-like protein Atg8 to autophagic membranes is a key step during the expansion of phagophores. This reaction is driven by 2 interconnected Ub-like conjugation systems. The second system conjugates the Ub-like protein Atg12 to Atg5.

Molecular regulation of autophagosome formation [PDF]
Macroautophagy, hereafter autophagy, is a degradative process conserved among eukaryotes, which is essential to maintain cellular homeostasis. Defects in autophagy lead to numerous human diseases, including various types of cancer and neurodegenerative ...

Membrane supply and remodeling during autophagosome biogenesis [PDF]
The de novo generation of double-membrane autophagosomes is the hallmark of autophagy. The initial membranous precursor cisterna, the phagophore, is very likely generated by the fusion of vesicles and acts as a membrane seed for the subsequent expansion ...
