What Is a Chloride Channel?

A chloride channel is a transmembrane protein that selectively conducts Cl⁻ ions across cell membranes. Several peptide toxins target chloride channels: chlorotoxin (36-AA scorpion peptide) blocks glioma-specific chloride channels and is used as a tumor-painting agent in neurosurgery. Peptide modulators of CFTR chloride channel are studied for cystic fibrosis.

Peptide Tools

  • Chlorotoxin: 36-residue scorpion peptide with 4 disulfides. Binds MMP-2/ClC-3 on glioma cells. ICG-conjugated for tumor visualization
  • CFTR peptides: Regulatory domain phosphopeptides modulating CFTR channel gating
  • GlyR peptides: Glycine receptor (chloride channel) modulatory peptides for pain research
