01

Overview

Mucin protein disulfide bonds are covalent linkages formed between cysteine residues within or between mucin protein chains. These bonds are essential for mucin polymerization, creating the viscoelastic mucus barrier that protects epithelial surfaces. Intermolecular disulfide bonds link mucin monomers into large aggregates, while intramolecular bonds stabilize domains within individual molecules. Disruption of these bonds can affect mucus properties and barrier function, impacting disease states such as cystic fibrosis, asthma, and inflammatory bowel disease.
