SGCA

SGCA (Sarcoglycan Alpha) is a protein that in humans is encoded by the SGCA gene. It is a component of the sarcoglycan complex, a subcomplex of the dystrophin-glycoprotein complex (DGC) which forms a link between the F-actin cytoskeleton and the extracellular matrix.

Function

The SGCA gene provides instructions for making a protein called alpha-sarcoglycan. This protein is found in muscle cells, where it plays a crucial role in maintaining the stability and integrity of these cells. Alpha-sarcoglycan is part of a group of proteins that work together to strengthen muscle fibers and prevent them from being damaged during muscle contraction and relaxation.

Clinical significance

Mutations in the SGCA gene cause Limb-girdle muscular dystrophy type 2D (LGMD2D), a form of muscular dystrophy characterized by progressive weakness and wasting of the muscles of the hip and shoulder girdles.
