Summaries for GBGT1 Gene

Entrez Gene Summary for GBGT1 Gene

  • This gene encodes a glycosyltransferase that plays a role in the synthesis of Forssman glycolipid (FG), a member of the globoseries glycolipid family. Glycolipids such as FG form attachment sites for the binding of pathogens to cells; expression of this protein may determine host tropism to microorganisms. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2013]

GeneCards Summary for GBGT1 Gene

GBGT1 (Globoside Alpha-1,3-N-Acetylgalactosaminyltransferase 1) is a Protein Coding gene. Among its related pathways are Metabolism and Glycosphingolipid biosynthesis - globo series. GO annotations related to this gene include globoside alpha-N-acetylgalactosaminyltransferase activity. An important paralog of this gene is GLT6D1.

UniProtKB/Swiss-Prot for GBGT1 Gene

  • Catalyzes the formation of some glycolipid via the addition of N-acetylgalactosamine (GalNAc) in alpha-1,3-linkage to some substrate. Glycolipids probably serve for adherence of some pathogens
