Function
Melanoma-associated antigen (MAGE) are produced by tumor cells and are recognized by cytotoxic T lymphocytes[1]. Many such antigens have been identified and are classified into 2 groups with group I called cancer/testis antigens[2]. The loss of MAGE expression is observed in primary melanoma[3].
Disease
Relevance
The expression of MAGE-A1 can be a marker for the prediction of resistance to taxan-based chemotherapy in pations with gastric cancer[4]. Assessment of MAGE may provide stratification factor for active-specific immunotherapy[5].
Structural highlights
The 3D structure of the complex between MAGE-A4 and the peptide inhibitor shows the peptide to bind in a cyclic conformation. The interacting with MAGE hydrophobic pocket. MAGE residue . Additional are formed between the peptide inhibitor and MAGE[6].
