Dystroglycan
View/Edit Human | View/Edit Mouse |
Dystroglycan is a protein that in humans is encoded by the DAG1 gene.[5][6][7]
Dystroglycan is one of the
Function
In skeletal muscle the dystroglycan complex works as a transmembrane linkage between the extracellular matrix and the cytoskeleton. [alpha]-dystroglycan is extracellular and binds to merosin
Expression
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. Dystroglycan expression in Mus musculus brain and neural retina has also been reported. However, the physiological role of dystroglycan in non-muscle tissues remains unclear.
In December 2022, the implications of abnormal dystroglycan expression and/or O-mannosylation on the pathogenesis of cancer have been reviewed.[9]
