Melanoma antigen recognized by T-cells 1 (UniProt: Q16655; also known as MART-1, Antigen LB39-AA, Antigen SK29-AA, Protein Melan-A) is encoded by the MLANA (also known as MART1) gene (Gene ID: 2315) in human. MART-1, a melanosome-specific protein, is a single-pass type III membrane protein with a transmembrane domain (aa 27-47) and a cytoplasmic domain (aa 48-118). Its expression is restricted to melanocytes, melanoma, and retina and is absent in other tissues and tumors. It is highly enriched in early melanosomes (Stage I and/or II melanosomes) indicating that its role in early melanogenesis. It is reported to stabilize both GPCR143/OA-1 and plays a role in the expression, stability, trafficking, and processing of pre-melanosome protein (PMEL) to ensure the formation of a stage 2 melanosome. It is mainly found in the endoplasmic reticulum (ER) and Golgi but is also detected in small vesicles and tubules dispersed over the entire cytoplasm. A small fraction of the protein is inserted into the membrane in an inverted orientation, which allows melanoma cells to be effectively recognized by specific cytotoxic T-cells. MART-1 may be a useful marker in the diagnosis of melanocytic lesions and in the differential diagnosis of malignant melanoma. (Ref.: Hoashi, T., et al. (2005). J. Biol.
