Protein: UDP-xylose and UDP-N-acetylglucosamine transporter (ER GDP-fucose transporter) (Solute carrier family 35 member B4 homolog) (Q9W429)
Organism: Drosophila melanogaster (Fruit fly)
Function: Sugar transporter that specifically mediates the transport of UDP-N-acetylglucosamine (UDP-GlcNAc), GDP-fucose and UDP-xylose. Functions redundantly with nac in the O-fucosylation of Notch, positively regulating Notch signaling. Involved in the biosynthesis of heparan sulfate-glycosaminoglycan (HS-GAG) and in Dpp signaling in the wing imaginal disk.
Subcellular location: Endoplasmic reticulum membrane {ECO:0000269|PubMed:19948734}; Multi-pass membrane protein {ECO:0000269|PubMed:19948734}.
