Mannosyl-oligosaccharide 1,2-alpha-mannosidase IA is an enzyme that in humans is encoded by the MAN1A1 gene.^[5]^[6]

This gene encodes a class I mammalian Golgi 1,2-mannosidase which is a type II transmembrane protein. This protein catalyzes the removal of 3 distinct mannose residues from peptide-bound Man(9)-GlcNAc(2) oligosaccharides and belongs to family 47 of glycosyl hydrolases.^[6]

Acid alpha-glucosidase, also called α-1,4-glucosidase and acid maltase, is an enzyme that helps to break down glycogen in the lysosome. It is functionally similar to glycogen debranching enzyme, but is on a different chromosome, processed differently by the cell and is located in the lysosome rather than the cytosol. In humans, it is encoded by the GAA gene. Errors in this gene cause glycogen storage disease type II.
