Function
GLU2B_SCHPO Subunit of glucosidase 2, which cleaves sequentially the 2 innermost alpha-1,3-linked glucose residues from the Glc(2)Man(9)GlcNAc(2) oligosaccharide precursor of immature glycoproteins in the endoplasmic reticulum (ER). Specifically required for the cleavage of the final glucose. The subunit beta retains the catalytic subunit alpha in the ER.[1] [2] [3]
