Interchangeable adaptors regulate mitochondrial dynamin assembly for membrane scission. [PDF]
Proc Natl Acad Sci U S A, 2013 Significance Mitochondrial fission is critical for mammalian cell division, mitophagy, and development. Fission initiates via recruitment of dynamin-related GTPases to the mitochondrial surface. In yeast and human, the recruitment utilizes adaptors that differ in sequence and predicted structure.

ESCRT membrane scission revealed by optical tweezers. [PDF]
The FASEB Journal, 2018 ESCRT proteins catalyze the function of membrane budding and scission from the inside of the cytosol to the outside. This process is fundamental in cell biology, comprising multivesicular endosome biogenesis, cytokinesis, viral budding (e.g. HIV, Ebola, Dengue) and other pathways.

Fusion and scission of membranes: Ubiquitous topological transformations in cells [PDF]
Traffic, 2017 The 2016 Nobel Prizes were awarded to Yoshinori Ohsumi for autophagy and to David Thouless, Duncan Haldane and Michael Kosterlitz for topological transitions. Both of these phenomena are intrinsically related when it comes to membranes. Here, we give a brief account on topological transformations of lipid membranes, commonly known as membrane fusion ...

Endosomal recycling tubule scission and integrin recycling involve the membrane curvature supporting protein LITAF [PDF]
, 2021 Recycling to the cell surface requires the scission of tubular membrane intermediates emanating from endosomes. Here we identify the monotopicmembrane protein LITAF (LPS-Induced TNF Activating Factor) and the related CDIP1 (Cell Death Involved p53 target

Insights into the function of ESCRT and its role in enveloped virus infection
Frontiers in Microbiology, 2023 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).

Alterations of membrane curvature during influenza virus budding [PDF]
, 2014 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 ...

A feedback loop between dynamin and actin recruitment during clathrin-mediated endocytosis.
PLoS Biology, 2012 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 ...

Crucial Role for Membrane Fluidity in Proliferation of Primitive Cells
Cell Reports, 2012 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
