Identification
HMDB Protein ID HMDBP13557
Secondary Accession Numbers None
Name Globoside alpha-1,3-N-acetylgalactosaminyltransferase 1
Synonyms
  1. Forssman glycolipid synthase
Gene Name GBGT1
Protein Type Unknown
Biological Properties
General Function Not Available
Specific Function Catalyzes the formation of Forssman glycolipid via the addition of N-acetylgalactosamine (GalNAc) in alpha-1,3-linkage to GalNAcb-1,3Gala-1,4Galb-1,4GlcCer (Gb4Cer) (PubMed:8855242, PubMed:10506200). Forssman glycolipid (also called Forssman antigen; FG) probably serves for adherence of some pathogens such as E.coli uropathogenic strains (PubMed:10506200).
