Dystroglycan protein complex
WebThe POMT complex helps modify a protein called alpha (α)-dystroglycan. Specifically, this complex adds a sugar molecule called mannose to α-dystroglycan through a process called glycosylation. Glycosylation is critical for the normal function of α-dystroglycan. WebJan 25, 2024 · Alpha-dystroglycan is a peripheral membrane protein that interacts with laminin in the basal lamina and beta-dystroglycan. Beta-dystroglycan crosses the membrane bilayer, associates with dystrophin (DMD; 300377), and is thereby connected to the alpha cytoskeleton.

During epithelial morphogenesis of kidney, the dystroglycan complex is shown to act as a receptor for the basement membrane. Dystroglycan expression in mouse brain and neural retina has also been reported.
WebThe dystroglycan protein complex provides a link between the cytoskeleton and the extracellular matrix (ECM). Defective O-glycosylation of alpha-dystroglycan (alpha-DG) severs this link leading to muscular dystrophies named dystroglycanopathies. These are characterized not only by muscle degeneration, but also by brain and ocular defects.
