| - | + | [https://www.uniprot.org/uniprot/DAG1_HUMAN DAG1_HUMAN] Defects in DAG1 are the cause of muscular dystrophy-dystroglycanopathy limb-girdle type C7 (MDDGC7) [MIM:[https://omim.org/entry/613818 613818]. An autosomal recessive muscular dystrophy showing onset in early childhood, and associated with mental retardation without structural brain anomalies. Note=MDDGC7 is caused by DAG1 mutations that interfere with normal post-translational processing, resulting in defective DAG1 glycosylation and impaired interactions with extracellular-matrix components. Other muscular dystrophy-dystroglycanopathies are caused by defects in enzymes involved in protein O-glycosylation.<ref>PMID:21388311</ref> | |

| - | + | [https://www.uniprot.org/uniprot/DAG1_HUMAN DAG1_HUMAN] The dystroglycan complex is involved in a number of processes including laminin and basement membrane assembly, sarcolemmal stability, cell survival, peripheral nerve myelination, nodal structure, cell migration, and epithelial polarization.<ref>PMID:9851927</ref> <ref>PMID:11724572</ref> <ref>PMID:16254364</ref> <ref>PMID:17360738</ref> Alpha-dystroglycan is an extracellular peripheral glycoprotein that acts as a receptor for both extracellular matrix proteins containing laminin-G domains, and for certain adenoviruses. Receptor for laminin-2 (LAMA2) and agrin in peripheral nerve Schwann cells. Also acts as a receptor for M.leprae in peripheral nerve Schwann cells but only in the presence of the G-domain of LAMA2, and for lymphocytic choriomeningitis virus, Old World Lassa fever virus, and clade C New World arenaviruses.<ref>PMID:9851927</ref> <ref>PMID:11724572</ref> <ref>PMID:16254364</ref> <ref>PMID:17360738</ref> Beta-dystroglycan is a transmembrane protein that plays important roles in connecting the extracellular matrix to the cytoskeleton. Acts as a cell adhesion receptor in both muscle and non-muscle tissues. Receptor for both DMD and UTRN and, through these interactions, scaffolds axin to the cytoskeleton. Also functions in cell adhesion-mediated signaling and implicated in cell polarity.<ref>PMID:9851927</ref> <ref>PMID:11724572</ref> <ref>PMID:16254364</ref> <ref>PMID:17360738</ref> | |
