Entry Information
Gene Namegalactose-3-O-sulfotransferase 1
Protein EntryG3ST1_HUMAN
UniProt IDQ99999
Comment typeDescription
Catalytic Activity3'-phosphoadenylyl sulfate + a galactosylceramide = adenosine 3',5'-bisphosphate + a galactosylceramidesulfate.
Catalytic Activity3'-phosphoadenylyl sulfate + monogalactosylalkylacylglycerol = adenosine 3',5'-bisphosphate + monogalactosylalkylacylglycerol sulfate.
FunctionCatalyzes the sulfation of membrane glycolipids. Seems to prefer beta-glycosides at the non-reducing termini of sugar chains attached to a lipid moiety. Catalyzes the synthesis of galactosylceramide sulfate (sulfatide), a major lipid component of the myelin sheath and of monogalactosylalkylacylglycerol sulfate (seminolipid), present in spermatocytes (By similarity). Also acts on lactosylceramide, galactosyl 1-alkyl-2-sn-glycerol and galactosyl diacylglycerol (in vitro). {ECO
PathwayLipid metabolism; sphingolipid metabolism.
SimilarityBelongs to the galactose-3-O-sulfotransferase family.
Subcellular LocationGolgi apparatus membrane ; Single-pass type II membrane protein .
Tissue SpecificityExpressed in kidney proximal tubule, gastric mucosa and adenocarcinoma. Highly expressed in renal cell carcinoma cell lines.
