The sarcoglycans are a group of transmembrane glycoproteins that associate to form a sub-complex of the dystrophin glycoprotein complex, the sarcoglycan complex. (Adapted from FBrf0129834).
Notes on Group
In vertebrate skeletal muscle sarcoglycans form a heterotetrameric complex. The exact nature and stoichiometry of the Drosophila complex is unknown (FBrf0129834).
