Dystrophin is a protein product of the X-linked gene mutation that is responsible for Duchenne and Becker muscular dystrophies. The protein binds actin and associates with dystrophin-glycoprotein complex to link the cytoskeleton to the extracellular matrix. Defects in the components of the dystrophin-glycoprotein complex are responsible for several phenotypes of muscular dystrophy.
肌营养不良蛋白是X连锁基因突变的蛋白质产物，该基因突变会导致杜氏和贝克型肌营养不良症。这种蛋白质与肌动蛋白结合，并与肌营养不良蛋白-糖蛋白复合物相关联，从而将细胞骨架与细胞外基质连接起来。肌营养不良蛋白-糖蛋白复合物成分的缺陷是导致几种肌营养不良症表型的原因。
