Protein
Lactosylceramide 4-alpha-galactosyltransferase
Organism
Rattus norvegicus
Function
Catalyzes the transfer of galactose from UDP-alpha-D-galactose to lactosylceramide/beta-D-galactosyl-(1->4)-beta-D-glucosyl-(1<->1)-ceramide(d18:1(4E)) to produce globotriaosylceramide/globoside Gb3Cer (d18:1(4E)) (PubMed:10854428). Also able to transfer galactose to galactosylceramide/beta-D-Gal-(1<->1')-Cer (By similarity). Globoside Gb3Cer is a glycosphingolipid of the globo serie, one of the major types of neutral root structures of glycosphingolipids, that constitute a significant portion of mammalian cell membranes (By similarity).
Similarity
Belongs to the glycosyltransferase 32 family.
