Summaries for SGCB Gene

Entrez Gene Summary for SGCB Gene

  • This gene encodes a member of the sarcoglycan family. Sarcoglycans are transmembrane components in the dystrophin-glycoprotein complex which help stabilize the muscle fiber membranes and link the muscle cytoskeleton to the extracellular matrix. Mutations in this gene have been associated with limb-girdle muscular dystrophy.[provided by RefSeq, Oct 2008]

GeneCards Summary for SGCB Gene

SGCB (Sarcoglycan Beta) is a Protein Coding gene. Diseases associated with SGCB include Muscular Dystrophy, Limb-Girdle, Type 2A and Autosomal Recessive Limb-Girdle Muscular Dystrophy Type 2E. Among its related pathways are Allograft rejection and Dilated cardiomyopathy (DCM).

UniProtKB/Swiss-Prot for SGCB Gene

  • Component of the sarcoglycan complex, a subcomplex of the dystrophin-glycoprotein complex which forms a link between the F-actin cytoskeleton and the extracellular matrix.
