Target intelligence / Profile preview
Western equine encephalitis virus glycoprotein E1 (WEEV E1)
- Target
- WEEV E1
- Molecular classification
- Viral fusion glycoprotein, Envelope protein, Viral structural protein
01
Overview
The Western equine encephalitis virus E1 glycoprotein is an envelope protein located on the surface of the virion, where it forms a heterodimer with E2. The E1 protein is responsible for mediating the fusion of the viral membrane with the host cell membrane during viral entry. This protein is a major determinant for virus infectivity and is critical for inducing neutralizing antibody responses in infected individuals. Mutations or improper glycosylation of E1 can impair viral infection and immune recognition[2][4][5][7].
- Other names
- WEEV envelope glycoprotein E1alphavirus E1 protein
