Human N-acetylglucosamine-1-phosphodiester alpha-N-acetylglucosaminidase (NAGPA) ELISA Kit

Hydrolases are transported to lysosomes after binding to mannose 6-phosphate receptors in the trans-Golgi network. NAGPA encodes the enzyme that catalyzes the second step in the formation of the mannose 6-phosphate recognition marker on lysosomal hydrolases. Commonly known as 'uncovering enzyme' or UCE, this enzyme removes N-acetyl-D-glucosamine (GlcNAc) residues from GlcNAc-alpha-P-mannose moieties and thereby produces the recognition marker. The encoded preproprotein is proteolytically processed by furin to generate the mature enzyme, a homotetramer of two disulfide-linked homodimers. Mutations in NAGPA are associated with developmental stuttering in human patients
