2-hydroxyacylsphingosine 1-beta-galactosyltransferase is an enzyme that in humans is encoded by the UGT8 gene.{{cite journal | vauthors = Bosio A, Binczek E, Le Beau MM, Fernald AA, Stoffel W | title = The human gene CGT encoding the UDP-galactose ceramide galactosyl transferase (cerebroside synthase): cloning, characterization, and assignment to human chromosome 4, band q26 | journal = Genomics | volume = 34 | issue = 1 | pages = 69–75 | date = Dec 1996 | pmid = 8661025 | doi = 10.1006/geno.1996.0242 }}{{cite web | title = Entrez Gene: UGT8 UDP glycosyltransferase 8 (UDP-galactose ceramide galactosyltransferase)| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=7368}}

Function

Galactocerebrosides are abundant sphingolipids of the myelin membrane of the central nervous system and peripheral nervous system and are also present in small amounts in kidney. The key enzymatic step in the biosynthesis of galactocerebrosides consists of the transfer of galactose to ceramide catalyzed by UDP-galactose ceramide galactosyltransferase (CGT, EC 2.4.1.45). The enzyme encoded by the CGT gene is the first involved in complex lipid biosynthesis in the myelinating oligodendrocyte.
