Target intelligence / Profile preview

Melanoma-associated antigen A1 (MAGEA1)

Target
MAGEA1
Molecular classification
Cancer/testis antigen (CTA), Group I MAGE-A family
01

Overview

Melanoma-associated antigen A1 (MAGEA1) is a cancer-testis antigen expressed in various tumor types but largely absent from normal adult tissues except for the testis. Its immunogenicity makes it a target for cancer immunotherapies, particularly T-cell based therapies. MAGEA1 expression can also serve as a biomarker for prognosis and prediction of chemoresistance.
