Laminin alpha2 chain mutations cause congenital muscular dystrophy with dysmyelination neuropathy (MDC1A). Previously, we demonstrated that laminin alpha1 chain ameliorates the disease in mice. Dystroglycan and integrins are major laminin receptors. Unlike laminin alpha2 chain, alpha1 chain binds the receptors by separate domains; laminin globular (LG) domains 4 and LG1-3, respectively. Thus, the laminin alpha1 chain is an excellent tool to distinguish between the roles of dystroglycan and integrins in the neuromuscular system.
