Anti-maltase-glucoamylase (alpha-glucosidase) antibodies enable researchers to detect and measure the maltase-glucoamylase (alpha-glucosidase) antigen in biological samples. This target is a reported synonym of the MGAM2 gene, which encodes maltase-glucoamylase 2 (putative). This protein is known to function in carbohydrate metabolism and homeostasis, among other biological roles. The human version of maltase-glucoamylase (alpha-glucosidase) has a canonical amino acid length of 2515 residues and a protein mass of 278 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the membrane of cells and notably expressed in the small intestine, rectum, duodenum, colon, and appendix. maltase-glucoamylase (alpha-glucosidase) is a member of the Glycosyl hydrolase 31 protein family.
