Melanoma cell antigen

"Melanoma cell antigen" refers to a set of proteins that are specifically or predominantly expressed in melanoma cells, with prominent examples including MLANA/MART-1 and the MAGE protein family. MLANA is a melanocyte-lineage antigen involved in melanosome formation and serves as a diagnostic and immunotherapeutic target. MAGE proteins are typically silent in normal somatic tissues but become activated in cancers, acting as tumor-specific antigens and protein interaction modules that modulate apoptotic and surviving pathways through association with E3 ubiquitin ligases. Both classes are heavily researched for cancer immunotherapy and biomarker development, but precise nomenclature is required for structured data and clinical translation[2][1][3][4][6][7][5].

Antigen presentation to T cells for immune-mediated destruction of melanoma cells (MLANA/MAGE); MAGE proteins modulate survival pathways by interacting with E3 ubiquitin ligases and affecting the stability of tumor suppressors like p53.
