Target intelligence / Profile preview

Mucin 1 (Tumor-Associated Epitope) (MUC1)

Target
MUC1
Molecular classification
Glycoprotein, Transmembrane protein, Mucin
01

Overview

Tumor-associated mucin 1 represents an altered form of this mucosal protein characterized by overexpression and abnormal hypoglycosylation in cancers. These changes create unique antigenic determinants that serve as promising targets for antibody-based therapies and cancer vaccines due to their restricted presence on malignant versus normal tissues while playing key roles in oncogenesis through multiple signaling pathways.
