Membrane Contact Sites in Autophagy
Cells, 2022 Eukaryotes utilize different communication strategies to coordinate processes between different cellular compartments either indirectly, through vesicular transport, or directly, via membrane contact sites (MCSs).

Journal of Fungi, 2023 Endocytosis and autophagy are the main pathways to deliver cargoes in vesicles and autophagosomes, respectively, to vacuoles/lysosomes in eukaryotes. Multiple positive regulators but few negative ones are reported to regulate the entry of vesicles and ...

Connexins : substrates and regulators of autophagy [PDF]
, 2016 Connexins mediate intercellular communication by assembling into hexameric channel complexes that act as hemichannels and gap junction channels. Most connexins are characterized by a very rapid turn-over in a variety of cell systems.

Atg8 Controls Phagophore Expansion during Autophagosome Formation [PDF]
Molecular Biology of the Cell, 2008 Autophagy is a potent intracellular degradation process with pivotal roles in health and disease. Atg8, a lipid-conjugated ubiquitin-like protein, is required for the formation of autophagosomes, double-membrane vesicles responsible for the delivery of cytoplasmic material to lysosomes.

Autophagy Reports, 2023 Macroautophagy/autophagy is a degradative pathway that plays an important role in maintaining cellular homeostasis in eukaryotes. During autophagy, cisternal compartments called phagophores are generated to sequester intracellular components; these ...

Cells, 2023 Autophagy–the lysosomal degradation of cytoplasm–plays a central role in cellular homeostasis and protects cells from potentially harmful agents that may accumulate in the cytoplasm, including pathogens, protein aggregates, and dysfunctional organelles ...

Ultrastructural relationship of the phagophore with surrounding organelles [PDF]
Autophagy, 2015 Phagophore nucleates from a subdomain of the endoplasmic reticulum (ER) termed the omegasome and also makes contact with other organelles such as mitochondria, Golgi complex, plasma membrane and recycling endosomes during its formation. We have used serial block face scanning electron microscopy (SB-EM) and electron tomography (ET) to image phagophore ...

Phagophore formation by the autophagy conjugation machinery [PDF]
, 2022 Abstract Autophagy is a fundamental cellular recycling pathway that captures cytoplasmic material by a phagophore membrane and delivers it to lysosomes for degradation. Nonselective phagophores are generated at specialized ER-domains termed omegasomes. Mechanistically, this process is not well understood. Here, we reconstituted the formation of

Structural basis for membrane recruitment of ATG16L1 by WIPI2 in autophagy
eLife, 2021 Autophagy is a cellular process that degrades cytoplasmic cargo by engulfing it in a double-membrane vesicle, known as the autophagosome, and delivering it to the lysosome.

Parkin interacts with Ambra1 to induce mitophagy [PDF]
, 2011 Mutations in the gene encoding Parkin are a major cause of recessive Parkinson's disease. Recent work has shown that Parkin translocates from the cytosol to depolarized mitochondria and induces their autophagic removal (mitophagy). However, the molecular
