CA242/CanAg Glycoform of MUC1 (CA242/CanAg-MUC1)

Target
CA242/CanAg-MUC1
Molecular classification
Glycoprotein, Mucin, Cell Surface Antigen
01

Overview

The CA242/CanAg glycoform of MUC1 is a cancer-associated, aberrantly glycosylated form of the transmembrane mucin protein MUC1. It presents the CA242 epitope, which is recognized by monoclonal antibodies like humanized C242 (HuC242). This specific glycoform is overexpressed in many epithelial cancers, particularly gastrointestinal tumors, making it a potential diagnostic biomarker and therapeutic target for antibody-based therapies and antibody-drug conjugates.
