Summary: Predicted to enable 2-hydroxyacylsphingosine 1-beta-galactosyltransferase activity and UDP-galactose:glucosylceramide beta-1,4-galactosyltransferase activity. Involved in cytoskeleton organization; nervous system development; and protein localization to paranode region of axon. Predicted to be located in endoplasmic reticulum. Predicted to be active in intracellular membrane-bounded organelle. Is expressed in brain. Orthologous to human UGT8 (UDP glycosyltransferase 8). [provided by Alliance of Genome Resources, Apr 2022]

GeneRIFs: Gene References Into Functions

What's a GeneRIF?

Our study showed that the additional deletion of Fa2h does not obviously affect the phenotype of Cgt-/- mice. This suggests that HFA-GlcCer and HFA-sphingomyelin do not functionally compensate the loss of HFA-GalCer in Cgt-/- mice.
Title: Myelination in the absence of UDP-galactose:ceramide galactosyl-transferase and fatty acid 2 -hydroxylase.
Ugcg and Ugt8a deficient oligodendroglial did not exhibit any phenotypic or myelin structural abnormalities; abundant and structurally intact myelin can form in their absence
Title: Absence of oligodendroglial glucosylceramide synthesis does not result in CNS myelin abnormalities or alter the dysmyelinating phenotype of CGT-deficient mice.
This study provides new insights into the changes that occur in the composition/distribution of myelin proteins in mice lacking ceramide galactosyltransferase.
Title: Myelin protein composition is altered in mice lacking either sulfated or both sulfated and non-sulfated galactolipids.
Our results indicate that loss of CGT in oligodendrocytes is exclusively responsible for the myelin structural deficits, demyelination, and behavioral abnormalities in CGT-deficient mice.
Title: Oligodendrocyte-specific ceramide galactosyltransferase (CGT) expression phenotypically rescues CGT-deficient mice and demonstrates that CGT activity does not limit brain galactosylceramide level.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
