Respiratory Syncytial Virus G Protein Subtype A (RSV-A G protein)

Target
RSV-A G protein
Molecular classification
Glycoprotein, Viral protein, Attachment protein
01

Overview

The Respiratory Syncytial Virus (RSV) G protein subtype A is a major surface glycoprotein of RSV, essential for viral attachment to host cells and modulating the host immune response. It contains a CX3C chemokine motif that binds CX3CR1, influencing leukocyte migration and immune modulation. The G protein exhibits high genetic variability, especially in hypervariable regions, making it a complex but attractive target for vaccines and monoclonal antibody therapies. Its dual roles in facilitating cell entry and modulating immune responses make it an important determinant of disease severity.
