gtb1, Glucosidase 2 subunit beta
Also Known as
GLU2B_SCHPO, gtb1, gls2-beta
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. Heterodimer of a catalytic subunit alpha (gls2) and a subunit beta (gtb1).
