Influenza virus-mediated membrane fusion: determinants of hemagglutinin fusogenic activity and experimental approaches for assessing virus fusion

BS Hamilton, GR Whittaker, S Daniel - Viruses, 2012 - mdpi.com
Hemagglutinin (HA) is the viral protein that facilitates the entry of influenza viruses into host
cells. This protein controls two critical aspects of entry: virus binding and membrane fusion …

Stepwise Priming by Acidic pH and a High K+ Concentration Is Required for Efficient Uncoating of Influenza A Virus Cores after Penetration

S Stauffer, Y Feng, F Nebioglu, R Heilig… - Journal of …, 2014 - Am Soc Microbiol
Influenza A virus (IAV) uses the low pH in late endocytic vacuoles as a cue for penetration by
membrane fusion. Here, we analyzed the prefusion reactions that prepare the core for …

Influenza-virus membrane fusion by cooperative fold-back of stochastically induced hemagglutinin intermediates

T Ivanovic, JL Choi, SP Whelan, AM van Oijen… - Elife, 2013 - elifesciences.org
Influenza virus penetrates cells by fusion of viral and endosomal membranes catalyzed by

Atomic structures of closed and open influenza B M2 proton channel reveal the conduction mechanism

VS Mandala, AR Loftis, AA Shcherbakov… - Nature structural & …, 2020 - nature.com
Abstract The influenza B M2 (BM2) proton channel is activated by acidic pH to mediate virus
uncoating. Unlike influenza A M2 (AM2), which conducts protons with strong inward …

Low-fidelity assembly of influenza A virus promotes escape from host cells

MD Vahey, DA Fletcher - Cell, 2019 - cell.com
Influenza viruses inhabit a wide range of host environments using a limited repertoire of
protein components. Unlike viruses with stereotyped shapes, influenza produces virions with …

Sequential conformational rearrangements in flavivirus membrane fusion

LH Chao, DE Klein, AG Schmidt, JM Peña, SC Harrison - Elife, 2014 - elifesciences.org
The West Nile Virus (WNV) envelope protein, E, promotes membrane fusion during viral cell
entry by undergoing a low-pH triggered conformational reorganization. We have examined …
