Quick Summary

Mucin is a type of protein that is a primary component of mucus. Mucus is a viscous fluid that moistens, lubricates, and protects various passages in the body, including the respiratory and digestive tracts. It is produced by mucous cells found on the mucous membrane lining these tracts.12

Mucin itself is a mucoprotein, meaning it is a protein combined with a carbohydrate prosthetic group, typically oligosaccharides. These proteins are highly viscous and are found in secretions like saliva and gastric juice. In the stomach, gastric mucus, containing mucin, forms a protective layer that shields the organ from its own acidic digestive juices. Mucous membranes, which secrete mucus, also trap inhaled particles and pathogens, preventing them from entering deeper tissues.342
