"Alternative" endocytic mechanisms exploited by pathogens: new avenues for therapeutic delivery? [PDF]
, 2007 Some pathogens utilize unique routes to enter cells that may evade the intracellular barriers encountered by the typical clathrin-mediated endocytic pathway.

eLife, 2022 The 12 related human ESCRT-III proteins form filaments that constrict membranes and mediate fission, including during cytokinetic abscission. The C-terminal tails of polymerized ESCRT-III subunits also bind proteins that contain Microtubule-Interacting ...

The HIV-1 late domain-2 S40A polymorphism in antiretroviral (or ART)-exposed individuals influences protease inhibitor susceptibility. [PDF]
, 2016 BackgroundThe p6 region of the HIV-1 structural precursor polyprotein, Gag, contains two motifs, P7TAP11 and L35YPLXSL41, designated as late (L) domain-1 and -2, respectively.

ESCRT machinery mediates selective microautophagy of endoplasmic reticulum in yeast
, 2019 ER-phagy, the selective autophagy of endoplasmic reticulum (ER), safeguards organelle homeostasis by eliminating misfolded proteins and regulating ER size. ER-phagy can occur by macroautophagic and microautophagic mechanisms.

ESCRT Proteins and Cell Signalling [PDF]
Traffic, 2011 Subunits of the endosomal sorting complex required for transport (ESCRT) were identified as components of a molecular machinery that sorts ubiquitinated membrane proteins into the intraluminal vesicles (ILVs) of multivesicular endosomes (MVEs) for subsequent delivery to the lumen of lysosomes or related organelles. As many of the membrane proteins that

Timing of ESCRT-III protein recruitment and membrane scission during HIV-1 assembly
eLife, 2018 The Endosomal Sorting Complexes Required for Transport III (ESCRT-III) proteins are critical for cellular membrane scission processes with topologies inverted relative to clathrin-mediated endocytosis.

A non-canonical ESCRT pathway, including histidine domain phosphotyrosine phosphatase (HD-PTP), is used for down-regulation of virally ubiquitinated MHC class I. [PDF]
, 2015 The Kaposi's sarcoma-associated herpes virus (KSHV) K3 viral gene product effectively down-regulates cell surface MHC class I. K3 is an E3 ubiquitin ligase that promotes Lys(63)-linked polyubiquitination of MHC class I, providing the signal for clathrin ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Nature Cell Biology, 2020 In this issue of Nature Cell Biology, Mercier et al. show that acute changes in membrane tension may be a physiological trigger for ESCRT assembly, which drives membrane scission, luminal vesicle budding, and a wide array of other membrane remodelling events throughout the cell.

Traffic, 2004 In eukaryotic cells, delivery of transmembrane proteins into the lumen of the lysosome for degradation is mediated by the multivesicular body pathway. The function of the ESCRT protein complexes is required for both the formation of multivesicular body lumenal vesicles and the sorting of endosomal cargo proteins into these vesicles.
