Membrane tension and membrane fusion [PDF]

Current Opinion in Structural Biology, 2015
Diverse cell biological processes that involve shaping and remodeling of cell membranes are regulated by membrane lateral tension. Here we focus on the role of tension in driving membrane fusion. We discuss the physics of membrane tension, forces that can generate the tension in plasma membrane of a cell, and the hypothesis that tension powers ...

Membrane Fusion Involved in Neurotransmission: Glimpse from Electron Microscope and Molecular Simulation

Frontiers in Molecular Neuroscience, 2017
Membrane fusion is one of the most fundamental physiological processes in eukaryotes for triggering the fusion of lipid and content, as well as the neurotransmission.

Fusion of secretory vesicles isolated from rat liver [PDF]

, 1978
Secretory vesicles isolated from rat liver were found to fuse after exposure to Ca2+. Vescle fusion is characterized by the occurrence of twinned vesicles with a continuous cleavage plane between two vesicles in freeze-fracture electron microscopy.

VAMP721 conformations unmask an extended motif for K+ channel binding and gating control [PDF]

, 2016
Soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) proteins play a major role in membrane fusion and contribute to cell expansion, signaling, and polar growth in plants.

Illuminating membrane fusion [PDF]

Proceedings of the National Academy of Sciences, 2006
Membrane fusion is a central event for a wide variety of biological processes, such as transport of cargo through the secretory and endocytic pathways, organelle inheritance, neurotransmission, and viral entry into host cells, among others. Hence, understanding the mechanism(s) of physiological membrane fusion is a subject of wide biological interest ...

Membrane fusion of secretory vesicles and liposomes Two different types of fusion [PDF]

, 1981
Secretory vesicles isolated from adrenal medulla were found to fuse in vitro in response to incubation with Ca2+. Intervesicular fusion was detected by electron microscopy and was indicated by the appearance of twinned vesicles in freeze-fractured ...

Structure and function of bacterial dynamin-like proteins [PDF]

, 2012
Membrane dynamics are essential for numerous cellular processes in eukaryotic and prokaryotic cells. In eukaryotic cells, membrane fusion and fission are often catalyzed by large GTPases of the dynamin protein family. These proteins couple GTP hydrolysis

Flavivirus membrane fusion

Journal of General Virology, 2006
Flavivirus membrane fusion is mediated by a class II viral fusion protein, the major envelope protein E, and the fusion process is extremely fast and efficient. Understanding of the underlying mechanisms has been advanced significantly by the determination of E protein structures in their pre- and post-fusion conformations and by the elucidation of the

Quantitation of mitochondrial dynamics by photolabeling of individual organelles shows that mitochondrial fusion is blocked during the Bax activation phase of apoptosis [PDF]

, 2004
A dynamic balance of organelle fusion and fission regulates mitochondrial morphology. During apoptosis this balance is altered, leading to an extensive fragmentation of the mitochondria.
