Anti-ssu-2 homolog antibodies are used for the immunodetection of the protein encoded by the SSUH2 gene. In humans, the canonical protein has a reported length of 375 amino acid residues and a mass of 42.7 kDa. Its subcellular localization is in the nucleus and cytoplasm. Alternative splicing is reported to yield 3 different isoforms for this protein. It is reported to be expressed in enterocytes of small and large intestinal mucosa. It is reported to play a role in odontogenesis. Other names for this target antigen include SSU-2, fls485, protein SSUH2 homolog, protein ssu-2 homolog, and C3orf32. Gene orthologs have been identified in the mouse, rat, bovine and chimpanzee species.
