Anti-BPNT2 antibodies are used in the immunodetection of the protein 3'(2'), 5'-bisphosphate nucleotidase 2. In humans, the canonical protein has a reported length of 359 amino acid residues and a mass of 38.7 kDa. Its subcellular localization is in the Golgi. It is notably widely expressed in many tissue types. A member of the Inositol monophosphatase protein superfamily, BPNT2 is known to be involved with post-embryonic development and skeletal system development. Post-translational modifications have been described, including glycosylation. The BPNT2 gene has been associated with the disease, Chondrodysplasia with joint dislocations. Synonyms for this target antigen include IMP 3, IMP-3, IMPA3, IMPAD1, Golgi-resident adenosine 3',5'-bisphosphate 3'-phosphatase, and GPAPP. BPNT2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
