Proteins/UNIPROT:Q9BRR3
Golgi-resident glycosylphosphatidylinositol (GPI)-N-acetylgalactosamine transferase that catalyzes the N-acetyl-beta-D-galactosamine transfer from an UDP-N-acetyl-alpha-D-galactosamine to the 4-OH-position of the first mannose of the glycosylphosphatidylinositol (GPI) of a GPI-anchored protein (GPI-AP). This modification occurs after the fatty acid remodeling step of the GPI-anchor maturation..
