Crystal Structure of a-dystroglycan
Overview
Dystroglycan (DG) is a cell surface receptor consisting of two subunits:, alpha-dystroglycan, extracellular and highly glycosylated, and, beta-dystroglycan, spanning the cell membrane. It is a pivotal member of, the dystrophin-glycoprotein complex and is involved in a wide variety of, important cellular processes such as the stabilization of the muscle fiber, sarcolemma or the clustering of acetylcholine receptors. We report the, 2.3-A resolution crystal structure of the murine skeletal muscle, N-terminal alpha-DG region, which confirms the presence of two autonomous, domains; the first finally identified as an Ig-like and the second, resembling ribosomal RNA-binding proteins. Solid-phase laminin binding, assays show the occurrence of protein-protein type of interactions, involving the Ig-like domain of alpha-DG.
