Short name: Sarcoglycan_alpha/epsilon

Family relationships

Description

This entry contains alpha and epsilon sarcoglycans.

The sarcoglycan family proteins are single pass transmembrane proteins that are part of the dystrophin-associated glycoprotein complex (DGC), a multiprotein complex that links the actin cytoskeleton to the extracellular matrix in cardiac and skeletal muscle [PMID: 11917091]. The DGC can be classified biochemically into three subcomplexes: the cytoplasmic subcomplex (contains dystrophin, the dystrobrevins and the syntrophins), the dystroglycan subcomplex and the sarcoglycan subcomplex. The function of the sarcoglycan subcomplex is not clear. However, mutations in alpha-, beta-, gamma- and delta-sarcoglycan cause different forms of autosomal recessive limb girdle muscular dystrophies (LGMD) demonstrating its importance for normal muscle function [PMID: 17200151].
