Viral membrane fusion: is glycoprotein G of rhabdoviruses a representative of a new class of viral fusion proteins? [PDF]
Enveloped viruses always gain entry into the cytoplasm by fusion of their lipid envelope with a cell membrane. Some enveloped viruses fuse directly with the host cell plasma membrane after virus binding to the cell receptor. Other enveloped viruses enter

IFITM proteins restrict viral membrane hemifusion.
The interferon-inducible transmembrane (IFITM) protein family represents a new class of cellular restriction factors that block early stages of viral replication; the underlying mechanism is currently not known.

Human parainfluenza virus 3 fusion protein cleavage: a key determinant of infection and spread [PDF]
Human parainfluenza virus 3 (HPIV3) entry into target cells depends on a viral fusion complex composed of hemagglutinin-neuraminidase (HN) and fusion protein (F).

Shielding and activation of a viral membrane fusion protein [PDF]
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 ...

Transient Transfection-based Fusion Assay for Viral Proteins
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 membrane fusion step of vaccinia virus entry is cooperatively mediated by multiple viral proteins and host cell components. [PDF]
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 ...

Identification and Characteristics of Fusion Peptides Derived From Enveloped Viruses
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

Viral Membrane Fusion and the Transmembrane Domain
Initiation of host cell infection by an enveloped virus requires a viral-to-host cell membrane fusion event. This event is mediated by at least one viral transmembrane glycoprotein, termed the fusion protein, which is a key therapeutic target.

Lipids as modulators of membrane fusion mediated by viral fusion proteins [PDF]
Enveloped viruses infect host cells by fusion of viral and target membranes. This fusion event is triggered by specific glycoproteins in the viral envelope. Fusion glycoproteins belong to either class I, class II or the newly described third class, depending upon their arrangement at the surface of the virion, their tri-dimensional structure and the ...
