Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0008499
UniProt IDQ9UK23
Primary gene name(s)NAGPA
Synonym gene name(s)unknown
Protein nameN-acetylglucosamine-1-phosphodiester alpha-N-acetylglucosaminidase
Protein functionCatalyzes the second step in the formation of the mannose 6-phosphate targeting signal on lysosomal enzyme oligosaccharides by removing GlcNAc residues from GlcNAc-alpha-P-mannose moieties, which are formed in the first step. Also hydrolyzes UDP-GlcNAc, a sugar donor for Golgi N-acetylglucosaminyltransferases. {ECO:0000269|PubMed:23572527}.
Subcellular locationGolgi apparatus, Golgi stack membrane {ECO:0000269|PubMed:12058031};
Single-pass type I membrane protein {ECO:0000269|PubMed:12058031}. Golgi apparatus, trans-Golgi network {ECO:0000269|PubMed:12058031}. Note=Cis/medial Golgi.
