Target intelligence / Profile preview

Mucin 1 (Tn-glycoform) (MUC1 (Tn))

Target
MUC1 (Tn)
Molecular classification
Mucin, Glycoprotein, Transmembrane protein
01

Overview

MUC1 is a transmembrane glycoprotein aberrantly glycosylated in many cancers, leading to the exposure of the Tn antigen (GalNAc-O-Ser/Thr). This Tn-MUC1 glycoform is a tumor-associated neoantigen, making it a target for immunotherapeutic strategies.

Other names
Tn-MUC1MUC1 with Tn antigen
02

Mechanism of action

Antibody binding to Tn-MUC1 inhibits cancer cell growth/survival; CAR-T cell mediated killing of Tn-MUC1 expressing cells
