WebMar 11, 2005 · We found that in Drosophila, Protein O -fucosyltransferase 1 (OFUT1), an enzyme that glycosylates epidermal growth factor–like domains of Notch, also has a distinct Notch chaperone activity. OFUT1 is an endoplasmic reticulum protein, and its localization was essential for function in vivo.
