Anti-3'(2'), 5'-bisphosphate nucleotidase 2 antibodies are used for the immunodetection of the protein encoded by the BPNT2 gene. 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. A member of the Inositol monophosphatase protein superfamily, it is known to be involved with post-embryonic development and skeletal system development. Post-translational modifications have been described, including glycosylation. The gene encoding this protein is implicated in Chondrodysplasia with joint dislocations. Other names for this target antigen include IMP 3, IMP-3, IMPA3, IMPAD1, Golgi-resident adenosine 3',5'-bisphosphate 3'-phosphatase, and GPAPP. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
