    PATHWAY
    metabolism
    signaling
    a component
  • associating with other sarcoglycans and carcospan in a stoichiometrically equal complex, stabilizing the link between dystroglycan and dystrophin/utrophin
  • two major subcomplexes : one consisting of SGCB, SGCD and SGCG and the other consisiting of SGCB and SGCD (association between SGCB and SGCG is particularly strong while SGCA is loosely associated with the other sarcoglycans)
