Acts as the major nucleotide-sugar transporter for the import of GDP-Fucose into the Golgi lumen. Transports GDP-Fucose in a strict counter-exchange mode. Is required for proper plant growth and development (PubMed:27381418). Acts also as a GDP-mannose transporter that may be involved in the import of GDP-mannose from the cytoplasm into the Golgi lumen (PubMed:15480787). Ubiquitous. RNAi plants display dwarfed phenotype with severe developmental growth defects. Cell wall composition of the RNAi plants shows a considerable reduction of the fucose content. GFT1 down-regulation has also an impact on the levels of protein fucosylation. Belongs to the nucleotide-sugar transporter family. GDP-Mannose:GMP antiporter (GMA) (TC 2.A.7.13) subfamily.
