SGCB

SGCB (Sarcoglycan Beta) is a protein that in humans is encoded by the SGCB 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 SGCB protein is a critical component of the sarcoglycan complex. This complex is part of the larger dystrophin-glycoprotein complex (DGC), which is crucial for the stability of muscle fiber membranes and for the linking of the actin cytoskeleton to the extracellular matrix.

Clinical significance

Mutations in the SGCB gene can lead to a type of muscular dystrophy known as limb-girdle muscular dystrophy type 2E (LGMD2E). This is a condition characterized by progressive muscle weakness and wasting, primarily affecting the muscles around the hips and shoulders (the "limb-girdle" muscles). Symptoms usually begin in childhood and can vary in severity.
