  • Target

    • Function

      Essential for the degradation of glygogen to glucose in lysosomes.
    • Involvement in disease

      Defects in GAA are the cause of glycogen storage disease type 2 (GSD2) [MIM:232300]; also called acid alpha-glucosidase (GAA) deficiency or acid maltase deficiency (AMD). GSD2 is a metabolic disorder with a broad clinical spectrum. The severe infantile form, or Pompe disease, presents at birth with massive accumulation of glycogen in muscle, heart and liver. Cardiomyopathy and muscular hypotonia are the cardinal features of this form whose life expectancy is less than two years. The juvenile and adult forms present as limb-girdle muscular dystrophy beginning in the lower limbs. Final outcome depends on respiratory muscle failure. Patients with the adult form can be free of clinical symptoms for most of their life but finally develop a slowly progressive myopathy.
    • Sequence similarities

      Belongs to the glycosyl hydrolase 31 family.
      Contains 1 P-type (trefoil) domain.
    • Post-translational

      The different forms of acid glucosidase are obtained by proteolytic processing.
      Phosphorylation of mannose residues ensures efficient transport of the enzyme to the lysosomes via the mannose 6-phosphate receptor.
    • Cellular localization

      Lysosome. Lysosome membrane.
