Function:Could be a melanogenic enzyme. Could represent an oncofetal self-antigen that is normally expressed at low levels in quiescent adult melanocytes but overexpressed by proliferating neonatal melanocytes and during tumor growth. Release of the soluble form , ME20-S , could protect tumor cells from antibody mediated immunity. ,similarity:Belongs to the Pmel-17/NMB family. ,similarity:Contains 1 PKD domain. ,subcellular location:Identified by mass spectrometry in melanosome fractions from stage I to stage IV. ,subcellular location:Probably product of proteolytic cleavage. ,tissue specificity:Preferentially expressed in melanomas. Some expression was found in dysplastic nevi. Not found in normal tissues nor in carcinomas. ,
