General annotation (Comments)

Function	Catalyzes 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 HSO3-3-galactosylceramide (sulfatide), a major lipid component of the myelin sheath and of HSO3-3-monogalactosylalkylacylglycerol (seminolipid), present in spermatocytes. Also acts on lactosylceramide, galactosyl 1-alkyl-2-sn-glycerol and galactosyl diacylglycerol (in vitro) By similarity.
Catalytic activity	3'-phosphoadenylyl sulfate + a galactosylceramide = adenosine 3',5'-bisphosphate + a galactosylceramidesulfate. 3'-phosphoadenylyl sulfate + monogalactosylalkylacylglycerol = adenosine 3',5'-bisphosphate + monogalactosylalkylacylglycerol sulfate.
Pathway	Lipid metabolism; sphingolipid metabolism.
Subcellular location	Golgi apparatus membrane; Single-pass type II membrane protein By similarity.
Sequence similarities	Belongs to the galactose-3-O-sulfotransferase family.
