2.A.7.12.6
Golgi UDP-galactose and UDP-N-acetylgalactosamine:UDP antiporter UGT or SLC35A2 (orthologue of 2.A.7.12.5) (Segawa et al., 2002). Transports nucleotide sugars from the cytosol into Golgi vesicles where glycosyltransferases function. Residues essential for activity, and mechanisms of transport by UGT allow greater understanding of the relationship between mutations in this protein and disease (Li and Mukhopadhyay 2019). May also take up cisplatin (Girardi et al. 2020). Potential interaction partners have been identified (Wiktor et al. 2021).
