Protein Structure
UniProt Annotation
Function Non-catalytic subunit of the N-acetylglucosamine-1- phosphotransferase complex, an enzyme that catalyzes the formation of mannose 6-phosphate (M6P) markers on high mannose type oligosaccharides in the Golgi apparatus. Binds and presents the high mannose glycans of the acceptor to the catalytic alpha and beta subunits (GNPTAB). Enhances the rate of N-acetylglucosamine- 1-phosphate transfer to the oligosaccharides of acid hydrolase acceptors. {ECO:0000269PubMed:15716021}.
Subcellular Localization Secreted. Golgi apparatus.
Disease Associations
Tissue Specificity Widely expressed. Highly expressed in the liver, intestine, brain, thymus, testis and ovary. {ECO:0000269PubMed:15716021}.
