Capsid
Capsid — The protein shell of a virus composed of self-assembling peptide subunits, studied as a model for peptide-based nanostructure design.
What Is a Capsid?
A capsid is the protein shell of a virus, composed of repeating protein subunits (capsomeres). In peptide research, capsid-derived peptides and capsid-binding peptides have applications in antiviral drug development, targeted nanoparticle delivery (virus-like particles), and phage display technology where peptides are displayed on phage capsid proteins.
Applications
- Phage display: Peptide libraries fused to pIII or pVIII capsid proteins of M13 phage
- VLPs: Virus-like particles displaying peptide epitopes for vaccine development
- Antiviral peptides: Capsid assembly inhibitors blocking viral particle formation
