The endosomal sorting complex required for transport (ESCRT) is formed by ESCRT-0, ESCRT-I, ESCRT-II, ESCRT-III complexes, and accessory proteins. It conducts vesicular trafficking in eukaryotes through the formation of vesicles and membrane fission and ...

ESCRT-0 is not required for ectopic Notch activation and tumor suppression in Drosophila.
Multivesicular endosome (MVE) sorting depends on proteins of the Endosomal Sorting Complex Required for Transport (ESCRT) family. These are organized in four complexes (ESCRT-0, -I, -II, -III) that act in a sequential fashion to deliver ubiquitylated ...

ESCRT-III Dysfunction Causes Autophagosome Accumulation and Neurodegeneration [PDF]
Defects in the endosomal-lysosomal pathway have been implicated in a number of neurodegenerative disorders. A key step in the endocytic regulation of transmembrane proteins occurs in a subset of late-endosomal compartments known as multivesicular bodies (MVBs), whose formation is controlled by endosomal sorting complex required for transport (ESCRT ...

ESCRT function in cytokinesis : location, dynamics and regulation by mitotic kinases [PDF]
Mammalian cytokinesis proceeds by constriction of an actomyosin ring and furrow ingression, resulting in the formation of the midbody bridge connecting two daughter cells. At the centre of the midbody resides the Flemming body, a dense proteinaceous ring

Helical Structures of ESCRT-III Are Disassembled by VPS4 [PDF]
During intracellular membrane trafficking and remodeling, protein complexes known as the ESCRTs (endosomal sorting complexes required for transport) interact with membranes and are required for budding processes directed away from the cytosol, including the budding of intralumenal vesicles to form multivesicular bodies; for the budding of some ...

ESCRT-III and ER–PM contacts maintain lipid homeostasis [PDF]
Saturating transposon mutagenesis screen identified the ESCRTs as synthetic genetic interactors in ER–PM contact mutant. The synthetic phenotype is caused by defects in lipid synthesis. Other ESCRT complexes, and VPS4 do not have a synthetic growth phenotype, indicating that only ESCRT-III proteins function in this lipid regulation pathway.

Changes in ESCRT-III filament geometry drive membrane remodelling and fission in silico
Background ESCRT-III is a membrane remodelling filament with the unique ability to cut membranes from the inside of the membrane neck. It is essential for the final stage of cell division, the formation of vesicles, the release of viruses, and membrane ...

LEM2 recruits CHMP7 for ESCRT-mediated nuclear envelope closure in fission yeast and human cells [PDF]
Endosomal sorting complexes required for transport III (ESCRT-III) proteins have been implicated in sealing the nuclear envelope in mammals, spindle pole body dynamics in fission yeast, and surveillance of defective nuclear pore complexes in budding ...

Membrane Constriction and Thinning by Sequential ESCRT-III Polymerization [PDF]
AbstractThe Endosomal Sorting Complexes Required for Transport (ESCRTs) mediate diverse membrane remodeling events. These activities typically require ESCRT-III proteins to stabilize negatively-curved membranes, although recent work has indicated that certain ESCRT-IIIs also participate in positive-curvature membrane shaping reactions.
