Solute carrier family 35 (SLC35) members transport nucleotide sugars and adenosine 3'-phospho 5'-phosphosulfate from the cytosol to the endoplasmic reticulum and the Golgi apparatus. These sugars serve as substrates for the glycosylation and sulfation of proteins, lipids and proteoglycans. (Adapted from
