Epithelial Glycoprotein Mucin (Mucin)

Target
Mucin
Molecular classification
Glycoprotein, Membrane-associated mucin, Secreted mucin
01

Overview

Epithelial glycoprotein mucins are a family of high molecular weight, heavily glycosylated proteins found on the apical surface of epithelial cells. They provide barrier protection, lubrication, and immune modulation. Aberrant expression and glycosylation are frequently observed in cancer, making them potential therapeutic targets and diagnostic markers.
