Melanoma-associated antigen A2

Molecular classification
Cancer-testis antigen
01

Overview

MAGEA2 is a cancer-testis antigen that modulates key tumor suppressor pathways by interacting with proteins such as p53 and p73. Its variable promoter regions allow differential regulation across tissues. It is considered a potential biomarker or therapeutic target due to its restricted normal tissue expression but high prevalence in certain tumors, including melanoma, triple-negative breast cancer, and head and neck squamous cell carcinoma.
