Insights into the function of ESCRT and its role in enveloped virus infection
The endosomal sorting complex required for transport (ESCRT) is an essential molecular machinery in eukaryotic cells that facilitates the invagination of endosomal membranes, leading to the formation of multivesicular bodies (MVBs).

A feedback loop between dynamin and actin recruitment during clathrin-mediated endocytosis.
Clathrin-mediated endocytosis proceeds by a sequential series of reactions catalyzed by discrete sets of protein machinery. The final reaction in clathrin-mediated endocytosis is membrane scission, which is mediated by the large guanosine triophosphate ...

Alterations of membrane curvature during influenza virus budding [PDF]
Influenza A virus belongs to the Orthomyxoviridae family. It is an enveloped virus that contains a segmented and negative-sense RNA genome. Influenza A viruses cause annual epidemics and occasional major pandemics, are a major cause of morbidity and ...

Crucial Role for Membrane Fluidity in Proliferation of Primitive Cells
The cell wall is a defining structural feature of the bacterial subkingdom. However, most bacteria are capable of mutating into a cell-wall-deficient “L-form” state, requiring remarkable physiological and structural adaptations. L-forms proliferate by an

Experimental study of the effects of hypochlorite on polysulfone membrane properties [PDF]
Although chemical solutions are widely employed to clean membranes, they can also be responsible for changes in membrane properties. The two major drawbacks are then either the functional properties of the membrane gradually change, so the production can

Regulation of membrane scission in yeast endocytosis
AbstractDuring clathrin-mediated endocytosis, a flat plasma membrane is shaped into an invagination that undergoes scission to form a vesicle. In mammalian cells, the force that drives the transition from invagination to vesicle is primarily provided by the GTPase dynamin that acts in concert with crescent-shaped BAR domain proteins.

CryoEM structure of the super-constricted two-start dynamin 1 filament
Dynamin mediates the fission of vesicles during endocytosis. Here, the authors report the cryoEM structure of a super-constricted two-start dynamin 1 filament- one of the two known helical forms of dynamin, with insights into the molecular mechanisms of ...

Influenza virus M2 protein mediates ESCRT-independent membrane scission. [PDF]
Many viruses utilize host ESCRT proteins for budding; however, influenza virus budding is thought to be ESCRT-independent. In this study we have found a role for the influenza virus M2 proton-selective ion channel protein in mediating virus budding. We observed that a highly conserved amphipathic helix located within the M2 cytoplasmic tail mediates a ...

Dynamin recruitment by clathrin coats: a physical step? [PDF]
Recent structural findings have shown that dynamin, a cytosol protein playing a key-role in clathrin-mediated endocytosis, inserts partly within the lipid bilayer and tends to self-assemble around lipid tubules. Taking into account these observations, we
