N-acetylglucosamine-1-phosphotransferase, gamma subunit, or N-acetylglucosamine-1-phosphate transferase, gamma subunit, is a human gene encoded by GNPTG. It may also be known as: N-acetylglucosamine-1-phosphotransferase subunit gamma; GlcNAc-1-phosphotransferase subunit gamma; UDP-N-acetylglucosamine-1-phosphotransferase subunit gamma; GlcNAc-phosphotransferase gamma-subunit; C16orf27; GNPTAG; LP2537; RJD9. The encoded protein has an amino acid length of 305 and a mass of 34.0 kDa. Other isoforms may exist. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
