Target intelligence / Profile preview

Glycoprotein B (human cytomegalovirus) (gB)

Target
gB
Molecular classification
Viral Fusion Protein, Glycoprotein
01

Overview

Glycoprotein B (gB) is a highly conserved, essential envelope protein of human cytomegalovirus (HCMV). It functions as the primary fusogen for HCMV, mediating virus attachment and membrane fusion with host cells, as well as cell-to-cell spread. It is a target for vaccine and therapeutic antibody development.
