Viral Fusion Protein (None)

Target
None
Molecular classification
Glycoprotein, Transmembrane protein, Viral protein, Class I fusion protein, Class II fusion protein, Class III fusion protein
01

Overview

Viral fusion proteins are specialized transmembrane glycoproteins found on the surface of enveloped viruses. Their primary function is to mediate the fusion of the viral envelope with host cell membranes, a critical step that allows viral genetic material to enter and infect host cells. These proteins are essential for viral entry and are major targets for neutralizing antibodies, making them key immunogens in vaccine development.
