GNPTG the gamma subunit of N-acetylglucosamine-1-phosphotransferase. May recognize the substrate of GlcNAc-1-phosphotransferase but also lysosomal proteins with mannose-6-phosphate residues. Defects in GNPTG cause a variant of pseudo-Hurler polydystrophy, an autosomal recessive disease of lysosomal hydrolase trafficking. Note: This description may include information from UniProtKB.
