GNPTG Products

GNPTG, also known as N-acetylglucosamine-1-phosphotransferase subunit gamma, is a 305 amino acid that is 34 kDa,; hexamer composed of two alpha, two beta and two gamma subunits, widely expressed; catalyzes the first step in synthesis of a mannose 6-phosphate lysosomal recognition marker, essential for targeting of lysosomal hydrolases to the lysosome. Studies are being performed on the relationship of this protein to mucolipidosis iii gamma, mucolipidosis, mucolipidosis iiic, mucolipidosis ii, dysostosis, short stature, autosomal recessive disease, scoliosis, parkinson's disease, ovarian carcinoma, and retinitis. GNPTG protein involvement has been observed with relation to UPF1 and GNPTAB proteins in the lysosome pathway.
