Dystrophin and the membrane skeleton

Abstract

Recent studies have confirmed several predictions concerning the structure and possible function of dystrophin, including a direct interaction with F-actin and an indirect interaction with laminin via linkage through a transmembrane protein complex. The results of the past year support a role for dystrophin in linking the actin cytoskeleton with the extracellular matrix in striated muscle, but they have not explained its function in other tissues.
