Recombinant human Fukutin (FKTN) protein is derived from the FKTN gene, whose mutations cause Fukuyama congenital muscular dystrophy (FCMD), a severe autosomal recessive disorder prevalent in Japan. FCMD is characterized by progressive muscle weakness, brain malformations, and ocular abnormalities, typically manifesting in infancy. The FKTN gene encodes Fukutin, a putative glycosyltransferase critical for α-dystroglycan post-translational modification—a key process in maintaining muscle membrane integrity and neuronal migration during development. Defective α-dystroglycan glycosylation disrupts extracellular matrix interactions, leading to muscle degeneration and neurological deficits.
Recombinant Fukutin is produced using expression systems like mammalian cells (e.g., HEK293) to ensure proper protein folding and glycosylation. It serves as a vital tool for studying FCMD pathogenesis, validating therapeutic strategies (e.g., gene therapy, enzyme replacement), and restoring α-dystroglycan function in vitro. Its applications extend to drug screening and disease modeling, offering insights into molecular mechanisms and potential treatments. By bridging molecular defects with clinical phenotypes, this recombinant protein accelerates research into neuromuscular disorders linked to defective glycosylation pathways.
