Measles Virus Hemagglutinin Glycoprotein

Molecular classification
Viral envelope protein, Glycoprotein, Attachment protein
01

Overview

The measles virus H glycoprotein is an essential envelope protein responsible for attachment to host cells. It binds to cellular receptors such as SLAM/CD150, CD46, and Nectin-4, initiating the process of viral entry. The H protein is a major target for neutralizing antibodies and is highly conserved, making it a crucial component in the efficacy of measles vaccines. Mutations in the receptor binding site are strongly selected against due to impairing infectivity. Structural studies have revealed important details about its receptor-binding mechanism.
