Mucin Protein (MUC)

Target
MUC
Molecular classification
Glycoprotein, Transmembrane protein, Secreted protein
01

Overview

Mucins are a family of high molecular weight, heavily glycosylated proteins produced by epithelial tissues. They play critical roles in protecting and lubricating epithelial surfaces, modulating immune responses, and participating in cell signaling pathways. Aberrant mucin expression and glycosylation are implicated in various diseases, particularly cancer.
