3'-phosphoadenylylsulfate:galactosylceramide 3'-sulfotransferase; 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 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); Belongs to the galactose-3-O-sulfotransferase family.
Synonyms: GAL3ST1, GAL3ST1p, hGAL3ST1, A0A024R1D7, C9J2M1 ...
