Melanoma-associated antigen 3 (UniProt: P43357; also known as Antigen MZ2-D, Cancer/testis antigen 1.3, CT1.3, MAGE-3 antigen) is encoded by the MAGEA3 (also known as MAGE3) gene (Gene ID: 4102) in human. MAGE-3 is a member of the melanoma-associated antigen gene family of cancer antigens that are expressed in several neoplastic, but not normal, tissues with the exception of testes. In melanoma cells, it enhances viability and serves as an antigen for cytolytic T lymphocytes. MAGEA3 expression is not reported in kidney tumors, leukemias and lymphomas. MAGEA3 expression is normally limited to early developmental stages. It enhances ubiquitin ligase activity of RING-type zinc finger-containing E3 ubiquitin-protein ligases. It is also reported to enhance ubiquitin ligase activity of TRIM28 and stimulate p53/TP53 ubiquitination by TRIM28. It is proposed to act through recruitment and/or stabilization of the Ubl-conjugating enzyme (E2) at the E3:substrate complex.
