Identification
HMDB Protein ID HMDBP13660
Secondary Accession Numbers None
Name N-acetyllactosaminide alpha-1,3-galactosyltransferase
Synonyms
  1. UDP-galactose:beta-D-galactosyl-1,4-N-acetyl-D-glucosaminide alpha-1,3-galactosyltransferase
  2. Galactosyltransferase
Gene Name GGTA1
Protein Type Unknown
Biological Properties
General Function Not Available
Specific Function Synthesizes the galactose-alpha(1,3)-galactose group by catalyzing the transfer of a galactose residue, with an alpha-1,3 linkage, on terminal lactosaminide (Gal-beta-1,4-GlcNAc-R) disaccharide borne by a glycoprotein or a glycolipid. Preferentially glycosylates proteins, can synthesize galactose-alpha(1,3)-galactose on glycoproteins but cannot synthesize the glycolipid called isoglobotrihexosylceramide or isogloboside 3 (iGb3).
