Secondary Accession Numbers None
Name GDP-Man:Man(3)GlcNAc(2)-PP-Dol alpha-1,2-mannosyltransferase
  1. Asparagine-linked glycosylation protein 11 homolog
  2. Glycolipid 2-alpha-mannosyltransferase
Gene Name ALG11
Protein Type Unknown
Biological Properties
General Function Not Available
Specific Function Mannosyltransferase involved in the last steps of the synthesis of Man5GlcNAc(2)-PP-dolichol core oligosaccharide on the cytoplasmic face of the endoplasmic reticulum. Catalyzes the addition of the 4th and 5th mannose residues to the dolichol-linked oligosaccharide chain.
