Protein
O-glucosyltransferase rumi homolog
Function
Protein O-glucosyltransferase. Catalyzes the reaction that attaches glucose through an O-glycosidic linkage to a conserved serine residue found in the consensus sequence C-X-S-X-[PA]-C in epidermal growth factor-like repeats. Regulates Notch signaling by glucosylating Notch in the ER, glucosylation is required for the correct folding and cleavage of Notch.
Similarity
Belongs to the glycosyltransferase 90 family.
