Protein function (UniProt)

UDP-N-acetylglucosamine transporter

Transports diphosphate-N-acetylglucosamine (UDP-GlcNAc) from the cytosol into the lumen of the Golgi apparatus, functioning as an antiporter that exchanges UDP-N-acetyl-alpha-D-glucosamine for UMP (PubMed:10393322). May supply UDP-GlcNAc as substrate for Golgi-resident glycosyltransferases that generate highly branched, multiantennary complex N-glycans and keratan sulfate (PubMed:23766508, PubMed:34981577). However, the exact role of SLC35A3 still needs to be elucidated, it could be a member of a catalytically more efficient multiprotein complex rather than function independently as a single transporter (PubMed:32938718)
