Target intelligence / Profile preview

Norovirus GI.1 major capsid protein VP1

Molecular classification: Viral structural protein, Capsid protein

Overview

The Norovirus GI.1 major capsid protein VP1 is the principal structural protein forming the outer shell of the norovirus particle. It self-assembles into virus-like particles (VLPs) and mediates initial attachment to host cells by binding histo-blood group antigens (HBGAs). It is a target for vaccine and diagnostic development.
