2.A.7.16.2
Golgi GDP-fucose-specific transporter, Gfr or CG9620 (Luhn et al., 2004).  It is required for glycan fucosylation and can also fucosylate NOTCH, a transmembrane cell fate determining receptor (Ishikawa et al. 2010).  Another transporter, the endoplasmic reticular Efr (TC# 2.A.7.10.4), can also fucoslyate NOTCH but not glycans.
