Which protein, absent in muscle cells of Duchenne muscular dystrophy, mediates the anchoring of skeletal muscle fibers to the basement membrane?

Question

Quizplus · Accepted Answer

Dystrophin is present in normal muscle cells and absent in Duchenne muscular dystrophy. Dystrophin mediates anchorage of the actin cytoskeleton of skeletal muscle fibers to the basement membrane through a membrane glycoprotein complex. Syntrophin is a family of dystrophin-associated proteins. Laminin is an abundant glycoprotein. Troponin is a marker of muscle injury or death, particularly in the heart.
