Recombinant EEEV Spike Glycoprotein E1 Protein, N-His: Structure, Activity, and Applications

Introduction to Eastern Equine Encephalitis Virus (EEEV)

Eastern Equine Encephalitis Virus (EEEV) is a severe mosquito-borne pathogen that causes fatal encephalitis in humans and horses. Due to its high mortality rate and limited treatment options, EEEV poses a significant threat to public health, especially in regions where the virus is endemic. Research efforts are focused on identifying and developing effective therapeutic targets to combat this virus, with the E1 spike glycoprotein emerging as a key candidate.

Structure of EEEV Spike Glycoprotein E1

The spike glycoprotein E1 is an essential structural component of the Eastern Equine Encephalitis Virus, playing a pivotal role in viral entry into host cells. E1 is a class II fusion protein that mediates the fusion of the viral envelope with the host cell membrane, a critical step for viral infectivity. The E1 protein forms a heterodimer with the E2 glycoprotein, where E1 is primarily responsible for the fusion process following receptor binding by E2. The E1 protein’s structure includes multiple domains essential for membrane fusion, making it a critical target for antiviral strategies.
