Gene Information

human ... GAA(2548)

General description

Lysosomal α-glucosidase (GAA), a glycoprotein and member of glycoside hydrolase family GH31, comprises a trefoil type-P domain, catalytic GH31 domain, distal, proximal, and an N-terminal β-sheet domain. The GAA gene is mapped to human chromosome 17q25.3. It undergoes various proteolytical and N-glycan processing in the late endosomal/lysosomal compartment to become an active form.

Immunogen

GAA (AAH40431, 851 a.a. ~ 952 a.a) partial recombinant protein with GST tag. MW of the GST tag alone is 26 KDa.

Biochem/physiol Actions

Lysosomal α-glucosidase (GAA) uses mannose-6-phosphate receptors for its localization on the lysosomes. It mediates the hydrolysis of glycogen to glucose. Mutations in the GAA gene impair acid alpha-glucosidase enzyme activity. Deficiency of GAA leads to a rare lysosomal storage disease namely Pompe disease.

Physical form

Solution in phosphate buffered saline, pH 7.4
