Dystrophin is a rod-shaped 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. This complex is variously known as the costamere or the dystrophin-associated protein complex.

1. Patients with DMD have a very low capacity to make dystrophin.
   癥患者有一個非常低的能力，使肌營養(yǎng)不良蛋白。
2. This enables the gene to produce a working version of the dystrophin gene.
   這使得該基因產(chǎn)生的一個工作版本的抗肌營養(yǎng)不良蛋白基因。
