Summary: This gene encodes dystroglycan, a central component of dystrophin-glycoprotein complex that links the extracellular matrix and the cytoskeleton in the skeletal muscle. The encoded preproprotein undergoes O- and N-glycosylation, and proteolytic processing to generate alpha and beta subunits. Certain mutations in this gene are known to cause distinct forms of muscular dystrophy. Alternative splicing results in multiple transcript variants, all encoding the same protein.

findings demonstrate that a lack of matriglycan on alpha-dystroglycan is a common feature in rhabdomyosarcoma due to the downregulation of LARGE1, and that ectopic expression of LARGE1 can restore matriglycan modifications and the ability of alpha-dystroglycan to function as an extracellular matrix receptor

This review focuses on two particular non-integrin laminin receptors in the epithelial context: dystroglycan and 37/67 laminin receptor (37/67LR).The 37/67LR is a still incompletely understood laminin receptor that is important to regulate intestinal epithelial cell function and could be involved in various pathological conditions.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
