Nucleotide-sugar transporter family protein;(source:Araport11)
TAIR Curator Summary
Encodes an ER-localized facilitator of UDP-N-acetylglucosamine (UDP-GlcNAc) and UDP-N-acetylgalactosamine (UDP-GalNAc) transport. It also regulates the cytokinin signal in meristematic cells through modulating activity of cytokinin oxidases/dehydrogenases. Finally, it is an important part of the ER quality control system, which determines the fate of aberrant proteins in the secretory pathway.
Mediates the transport of UDP-linked acetylated hexosamines across the endoplasmic reticulum (ER) membrane (PubMed:25535363). Facilitates UDP-N-acetylglucosamine (UDP-GlcNAc) and UDP-N-acetylgalactosamine (UDP-GalNAc) transport (PubMed:25535363). Regulates the cytokinin signal in meristematic cells through modulating activity of cytokinin oxidases/dehydrogenases (PubMed:25535363). Part of the ER quality control system, which determines the fate of aberrant proteins in the secretory pathway (PubMed:25535363).
