Neisseria meningitidis Group B Outer Membrane Protein (MenB OMP)

Target
MenB OMP
Molecular classification
Porin, Outer Membrane Protein, Metallopeptidase
01

Overview

Neisseria meningitidis group B outer membrane proteins (OMPs) are key components of the bacterial cell envelope and play crucial roles in nutrient transport, host-pathogen interactions, and immune evasion. These proteins, particularly PorA and PorB, are major targets for vaccine development due to their surface exposure and immunogenicity. OMV-based vaccines containing these proteins have shown efficacy but require careful selection/matching of antigen variants for broad coverage.
