Function

The zeta-sarcoglycan gene measures over 465 kb and localizes to 8p22. This protein is part of the sarcoglycan complex, a group of 6 proteins. The sarcoglycans are all N-glycosylated transmembrane proteins with a short intra-cellular domain, a single transmembrane region and a large extra-cellular domain containing a carboxyl-terminal cluster with several conserved cysteine residues. The sarcoglycan complex is part of the dystrophin-associated glycoprotein complex (DGC), which bridges the inner cytoskeleton and the extracellular matrix.^[6]

Clinical significance

Zeta-sarcoglycan is reduced in mouse models of muscular dystrophy and SGCZ is found as a component of the vascular smooth muscle sarcoglycan complex. Hence SGCZ may be important in the pathogenesis of muscular dystrophy.^[5]
