Bioscience Reports, 2000 The fusion of biological membranes results in two bilayer-based membranes merging into a single membrane. In this process the lipids have to undergo considerable rearrangement. The nature of the intermediates that are formed during this rearrangement has been investigated. Certain fusion proteins facilitate this process. In many cases short segments of

Physico-chemical requirements and kinetics of membrane fusion of flavivirus-like particles. [PDF]
, 2015 Flaviviruses deliver their RNA genome into the host-cell cytoplasm by fusing their lipid envelope with a cellular membrane. Expression of the flavivirus pre-membrane and envelope glycoprotein genes in the absence of other viral genes results in the ...

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Molecular Biomedicine, 2022 Intracellular vesicle trafficking is the fundamental process to maintain the homeostasis of membrane-enclosed organelles in eukaryotic cells. These organelles transport cargo from the donor membrane to the target membrane through the cargo containing ...

, 2014 Entry of enveloped viruses is mediated by viral glycoproteins that catalyze fusion of viral and cellular membranes. These viral glycoproteins need to be activated which leads to extensive conformational changes that trigger the insertion or attachment of a fusion peptide in or to cellular target membranes thus bridging two bilayers.

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

PLoS Pathogens, 2023 Host cell entry of vaccinia virus (a poxvirus) proceeds through multiple steps that involve many viral proteins to mediate cell infection. Upon binding to cells, vaccinia virus membrane fuses with host membranes via a viral entry fusion protein complex ...

New mechanism of membrane fusion
, 2001 We have carried out Monte Carlo simulation of the fusion of bilayers of single chain amphiphiles which show phase behavior similar to that of biological lipids. The fusion mechanism we observe is very different from the ``stalk'' hypothesis.

Fusion of isolated myoblast plasma membranes [PDF]
, 1978 Fusion of plasma membranes isolated from myoblasts grown in culture has been investigated. 1. 1. Membrane fusion was specifically dependent on Ca2+ at physiological concentrations. However, at higher concentrations of cations, fusion could be triggered
