Description

General description

Dystroglycan (UniProt: Q28685; also known as Dystrophin-associated glycoprotein 1) is encoded by the DAG1 gene (Gene ID: 100009278) in rabbit. Dystroglycan is a component of the dystrophin glycoprotein complex that serves as an adhesion molecule and links the extracellular matrix to the intracellular actin cytoskeleton. Its expression is reported in the brain, cardiac muscle, skeletal muscle, and placenta. It is synthesized with a signal peptide (aa 1-29) that is subsequently cleaved off to generate the mature protein that is further autolytically cleaved (between 653-654) to produce a-dystroglycan (aa 30-653) and b-dystroglycan (aa 654-895). a-dystroglycan is an extracellular peripheral glycoprotein that binds to several extracellular matrix and synaptic proteins such as laminin-2 and 5, agrin, neurexin, and pikachurin. It is heavily O-glycosylated, which comprises of up to two thirds of its mass and the carbohydrate composition differs depending on tissue type. It is reported that its O-mannosyl glycosylation is required for its ligand- binding functions. b-dystroglycan is a single-pass type 1 transmembrane protein that plays important roles in connecting the extracellular matrix to the cytoskeleton and serves as a cell adhesion receptor in both muscle and non-muscle tissues. In the cell, b-dystroglycan binds to dystrophin that is linked to actin cytoskeleton. Hence, a/b dystroglycans act as a molecular axis connecting extracellular matrix with the cytoskeleton across the plasma membrane. Defects in O-mannosyl glycan have been linked to various congenital muscular dystrophies caused by aberrant a-dystroglycan glycosylation. (Ref.: Kanagawa, M., et al. (2010). J. Biol.
