Target description

Dystrophin (UniProt P11532) is encoded by the DMD (also known as BMD, CMD3B, DXS142, DXS164, DXS206, DXS230, DXS239, DXS268, DXS269, DXS270, DXS272, MRX85) gene (Gene ID 1756) in human. Dystrophin is a cytoplasmic protein and, a vital part of a protein complex that connects the cytoskeleton of a muscle fiber to the surrounding extracellular matrix through the cell membrane. It is expressed in muscle fibers accumulating in the costameres of myoplasm at the sarcolemma. Its expression is also reported in brain, muscle, kidney, lung and testis. Dystrophin is localized to the inner part of the muscle fiber cell membrane (sarcolemma), where it forms the dystrophin-associated glycoprotein complex (DGC) that links the extracellular matrix to the actin cytoskeleton. The N-terminus is the actin-binding domain, and the carboxy-terminal domain interacts with beta-dystroglycan as well as dystrobrevin and the syntrophin. The central rod domain that comprises the major mass of the dystrophin molecule forms a flexible, rod-shaped structure. Dystrophin plays an important role in stabilizing the muscle fiber against the mechanical forces of muscle contraction by providing a shock-absorbing connection between the cytoskeleton and the extracellular matrix. The DMD gene is the largest known gene in humans and mutations in this gene are known to cause Duchenne muscular dystrophy (DMD), a sex-linked recessive disorder that affects males aged 3 to 7 year as proximal muscle weakness with steady progression. The mutations in DMD gene disrupts the open reading frame (ORF) and prevent the full translation of dystrophin. ORF restoration by exon skipping using antisense oligonucleotides is designed to transform the DMD phenotype to that of the milder disorder, Becker muscular dystrophy (BMD), which is typically caused by in-frame dystrophin deletions that allow the production of an internally deleted, but partially functional dystrophin. Since abnormalities in the protein expression occur specifically in patients with these types of muscular dystrophy, dystrophin analysis may be used to distinguish these conditions from other neuromuscular diseases.
