Dystroglycan protein complex
WebThe sarcoglycan complex consists of α-, β-, γ-, and δ-sarcoglycan, and is integral to the dystrophin-associated glycoprotein complex, conferring structural stability to the sarcolemma and protecting muscle fibers from mechanical stress during muscle contraction. WebSpecifically, this complex adds a sugar molecule called mannose to α-dystroglycan through a process called glycosylation. Glycosylation is critical for the normal function of …

WebDystrophinopathies are diseases caused by mutations in the Duchenne Muscular Dystrophy gene (DMD) encoding the dystrophin protein. Depending on the type of mutation, patients develop either the severe DMD or the milder Becker Muscular Dystrophy. Although substantial effort was made, the pathophysiol … Dystroglycan is widely distributed in non-muscle tissues as well as in muscle tissues. During epithelial morphogenesis of kidney, the dystroglycan complex is shown to act as a receptor for the basement membrane.

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. WebMutations in many components of the dystrophin protein complex cause other forms of autosomally inherited muscular dystrophy, indicating the importance of this complex in normal muscle function. ...

WebNeurofilaments (NF) are classed as type IV intermediate filaments found in the cytoplasm of neurons.They are protein polymers measuring 10 nm in diameter and many micrometers in length. Together with microtubules (~25 nm) and microfilaments (7 nm), they form the neuronal cytoskeleton.They are believed to function primarily to provide structural … WebDystrophin and the dystrophin-associated protein complex (DAPC) have recently been implicated in cell signalling events. These proteins are ideally placed to transduce signals from the extracellular matrix (ECM) to the cytoskeleton. Here we show that beta-dystroglycan is tyrosine-phosphorylated in C …

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.
