What is "dystroglycan"

n. (context protein English) A glycoprotein associated with dystrophin

Dystroglycan is a protein that in humans is encoded by the DAG1 gene.

Dystroglycan is one of the dystrophin-associated glycoproteins, which is encoded by a 5.5 kb transcript in Homo sapiens on chromosome 3. There are two exons that are separated by a large intron. The spliced exons code for a protein product that is finally cleaved into two non-covalently associated subunits, [alpha] (N-terminal) and [beta] (C-terminal).
