MAGEA4 (LYZ) Antibody – Rabbit Polyclonal

MAGE-A4: a member of the MAGE (melanoma-associated antigen) family of Cancer-Testis Antigens (CTAs). May play a role in embryonal development and tumor transformation or aspects of tumor progression. CTAs were once thought to be silenced in most normal adult tissues, with limited expression in fetal, placental, testis, and ovary cells. These proteins are now known to be aberrantly expressed in various cancers and many are capable of eliciting humoral and cellular immune responses. The MAGE family of proteins, encompassing 12 highly homologous genes clustered at Xq26-28, are tumor-specific antigens that can be recognized by autologous cytolytic T lymphocytes. MAGE proteins are characterized by the presence of a conserved domain (MHD, MAGE Homology Domain). MAGE-A4 expression is high in ovarian serous carcinoma, various squamous carcinomas, testicular germ cell tumors, oesophageal mucosal melanoma, and triple-negative breast cancers. Spontaneous humoral and cellular immune responses against MAGE-A4 have been detected in cancer patients. MAGE family proteins bind to and activate RING E3 ubiquitin ligases.
