Anti-HGSNAT antibodies are used in the immunodetection of the protein heparan-alpha-glucosaminide N-acetyltransferase. In humans, the canonical protein has a reported length of 663 amino acid residues and a mass of 73.3 kDa. Its subcellular localization is in the lysosomes. It is found to be widely expressed, with highest level in leukocytes, heart, liver, skeletal muscle, lung, placenta and liver. HGSNAT is reported to be a lysosomal acetyltransferase that acetylates the non-reducing terminal alpha-glucosamine residue of intralysosomal heparin or heparan sulfate, converting it into a substrate for luminal alpha-N-acetyl glucosaminidase. Post-translational modifications have been described, including glycosylation and protein cleavage. Synonyms for this target antigen include transmembrane protein 76. HGSNAT gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some HGSNAT antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunocytochemistry is also a common application.
