Background: Melanotransferrin/CD228

Melanotransferrin, also known as MTF, CD228, Melanoma-associated Antigen p97, MAP97 and MFI2, is a 90-97 kDa sialoglycoprotein member of the transferrin family. Unlike other transferrins, which are secreted, MTF is usually found tethered to the cell membrane by a glycosyl phosphatidyl inositol anchor, with only small amounts of soluble protein detected. MTF is highly expressed on melanoma cells, and at lower levels in salivary gland, pancreas, kidney and testis. Like other transferrins, MTF is an iron-binding protein, and may play roles in cellular proliferation, tumorigenesis, metastasis and migration. Full-length human, mouse and rat MTF is 738 amino acids (aa). Over aa 1-711, human MTF shares 85 and 86% aa identity with mouse and rat MTF, respectively.
