UDP-N-acetylglucosamine/UDP-glucose/GDP-mannose transporter, Slc35d2, Solute carrier family 35 member D2, UDP-galactose transporter-related protein 8, UGTrel8, Slc35d2, Ugtrel8
Antiporter transporting nucleotide sugars such as UDP-N-acetylglucosamine (UDP-GlcNAc), UDP-glucose (UDP-Glc) and GDP-mannose (GDP-Man) pooled in the cytosol into the lumen of the Golgi in exchange for the corresponding nucleosides monophosphates (UMP for UDP-sugars and GMP for GDP-sugars). May take part in heparan sulfate synthesis by supplying UDP-Glc-NAc, the donor substrate, and thus be involved in growth factor signaling.
