Anti-PTPRQ antibodies are used in the immunodetection of the protein protein tyrosine phosphatase receptor type Q. In humans, the canonical protein has a reported length of 2332 amino acid residues and a mass of 260.9 kDa. Its subcellular localization is in the membrane. A member of the Protein-tyrosine phosphatase protein family, PTPRQ is known to be a phosphatidylinositol phosphatase required for auditory function. Post-translational modifications have been described, including glycosylation. The PTPRQ gene has been associated with the disease, Deafness. Synonyms for this target antigen include phosphotidylinositol phosphatase PTPRQ, protein-tyrosine phosphatase, receptor-type, expressed by glomerular mesangial cells, and phosphatidylinositol phosphatase PTPRQ. PTPRQ gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. These PTPRQ antibodies are widely used in Western Blot experiments, among other applications.
