Glucosidase I, also known as GCS1, is a human gene.^[1]

Glucosidase I is the first enzyme in the N-linked oligosaccharide processing pathway. GCS1 cleaves the distal alpha-1,2-linked glucose residue from the Glc(3)-Man(9)-GlcNAc(2) oligosaccharide precursor. GCS1 is located in the lumen of the endoplasmic reticulum.^[1]
