MELTF, or melanotransferrin, is a glycoprotein belonging to the transferrin family, initially identified for its role in iron transport and cellular iron homeostasis. Unlike its well-characterized homologs, such as serum transferrin, MELTF exhibits unique membrane-bound and soluble forms, enabling diverse biological interactions. It is encoded by the *MELTF* gene and is notably expressed in melanocytes, endothelial cells, and certain cancer cells. MELTF's primary function involves mediating iron uptake through non-classical pathways, bypassing the traditional transferrin receptor (TfR1) mechanism. This feature has drawn attention in contexts where cellular iron demand is high, such as in rapidly proliferating tumors or under iron-deficient conditions.
Recombinant MELTF protein is engineered using expression systems like mammalian cells (e.g., HEK293 or CHO cells) or bacteria (E. coli), depending on the need for post-translational modifications. The recombinant form retains the functional domains critical for iron-binding and receptor interaction, enabling researchers to study its biochemical properties, structure-function relationships, and therapeutic potential. Purification typically involves affinity chromatography tags (e.g., His-tag) to ensure high yield and purity.
Research on recombinant MELTF has implications for understanding cancer biology, as its overexpression is linked to tumor progression, metastasis, and resistance to therapies. It is also explored as a diagnostic marker or therapeutic target in melanoma and other malignancies. Additionally, its role in blood-brain barrier iron transport has sparked interest in neurodegenerative diseases like Alzheimer's, where iron dysregulation is implicated. By providing a controlled and scalable source of functional MELTF, recombinant protein technology facilitates mechanistic studies, drug screening, and the development of biologics aimed at modulating iron-related pathways in disease.
