label_lc: reduced muscle fiber alpha dystroglycan
description: "Immunohistochemistry reveals reduced alpha dystroglycan protein in the muscle biopsy. Alpha-dystroglycan is a heavily glycosylated peripheral-membrane component of the dystrophin-associated glycoprotein complex (DAPC), which, in addition to laminin alpha2, binds perlecan and agrin in the extracellular matrix, whereas beta-dystroglycan, derived from the same gene, is a transmembrane protein that links to dystrophin intracellularly."
