Transient Transfection-based Fusion Assay for Viral Proteins
Bio-Protocol, 2017 Membrane fusion is vital for entry of enveloped viruses into host cells as well as for direct viral cell-to-cell spread. To understand the fusion mechanism in more detail, we use an infection free system whereby fusion can be induced by a minimal set of ...

The transmembrane domain and acidic lipid flip-flop regulates voltage-dependent fusion mediated by class II and III viral proteins. [PDF]
PLoS ONE, 2013 Voltage dependence of fusion induced by class II and class III viral fusion proteins was investigated. Class II proteins from Ross River and Sindbus virus and a mutant class III protein from Epstein Barr virus were found to induce cell-cell fusion that ...

The membrane fusion step of vaccinia virus entry is cooperatively mediated by multiple viral proteins and host cell components. [PDF]
PLoS Pathogens, 2011 For many viruses, one or two proteins allow cell attachment and entry, which occurs through the plasma membrane or following endocytosis at low pH. In contrast, vaccinia virus (VACV) enters cells by both neutral and low pH routes; four proteins mediate ...

Shielding and activation of a viral membrane fusion protein [PDF]
Nature Communications, 2018 Viral fusion proteins undergo extensive conformational changes during entry but intermediate conformations often remain unknown. Here, the authors show how Gn of Rift Valley fever virus fusion protein shields hydrophobic fusion loops of Gc and how these ...

Inhibition of Measles Viral Fusion Is Enhanced by Targeting Multiple Domains of the Fusion Protein
ACS Nano, 2021 Measles virus (MeV) infection remains a significant public health threat despite ongoing global efforts to increase vaccine coverage. As eradication of MeV stalls, and vulnerable populations expand, effective antivirals against MeV are in high demand.

Class II Membrane Fusion Proteins in Viral and Cellular Fusion Events [PDF]
Biophysical Journal, 2013 Class II proteins are viral membrane fusogenic molecules folded essentially as beta-sheet and having an internal fusion peptide. In particular, they lack the characteristic central alpha-helical coiled coil present in the post-fusion conformation of all other viral fusion proteins. The regular, symmetric enveloped viruses that have been studied so far,

Identification and Characteristics of Fusion Peptides Derived From Enveloped Viruses
Frontiers in Chemistry, 2021 Membrane fusion events allow enveloped viruses to enter and infect cells. The study of these processes has led to the identification of a number of proteins that mediate this process. These proteins are classified according to their structure, which vary

Initial size and dynamics of viral fusion pores are a function of the fusion protein mediating membrane fusion [PDF]
Biology of the Cell, 2008 Background information. Protein‐mediated merger of biological membranes, membrane fusion, is an important process. To investigate the role of fusogenic proteins in the initial size and dynamics of the fusion pore (a narrow aqueous pathway, which widens to finalize membrane fusion), two different fusion proteins expressed in the same cell line were ...

ViralFP: A webserver of viral fusion proteins
, 2021 Viral fusion proteins are attached to the membrane of enveloped viruses (a group that includes Coronaviruses, Dengue, HIV and Influenza) and catalyze fusion between the viral and host membranes, enabling the virus to insert its genetic material into the host cell.
