Anti-nuclear FMR1 interacting protein 2 antibodies are used for the immunodetection of the protein encoded by the NUFIP2 gene. In humans, the canonical protein has a reported length of 695 amino acid residues and a mass of 76.1 kDa. Its subcellular localization is in the nucleus and cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. It is known to bind RNA. Other names for this target antigen include 82 kDa FMRP-interacting protein, 82-kD FMRP Interacting Protein, FMRP-interacting protein 2, NUFIP2, FMR1 interacting protein 2, and FMR1-interacting protein NUFIP2. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
