Protein

N-acetylglucosamine-1-phosphotransferase subunits alpha/beta

Gene

GNPTAB

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Catalyzes the formation of mannose 6-phosphate (M6P) markers on high mannose type oligosaccharides in the Golgi apparatus. M6P residues are required to bind to the M6P receptors (MPR), which mediate the vesicular transport of lysosomal enzymes to the endosomal/prelysosomal compartment.2 Publications

Catalytic activityi

UDP-N-acetyl-D-glucosamine + lysosomal-enzyme D-mannose = UMP + lysosomal-enzyme N-acetyl-D-glucosaminyl-phospho-D-mannose.1 Publication

Miscellaneous

Due to the low pH in the endosomal/prelysosomal compartment, the lysosomal enzyme-MPR complex dissociates and then the enzyme is delivered to the lysosome. Between 5% and 20% of newly synthesized lysosomal enzymes escape the binding to the MPR in the Golgi apparatus and are secreted.
Stealth proteins are part of a protein family that is conserved from bacteria to higher eukaryotes. Family members were first identified in microbes as proteins that help pathogens to elude the host innate immune system. Microbial stealth proteins are most likely involved in the biosynthesis of exopolysaccharides. Stealth proteins are predicted to function as hexose-1-phosphoryltransferases.
