Anti-ASB9 antibodies are used in the immunodetection of the protein ankyrin repeat and SOCS box containing 9. In humans, the canonical protein has a reported length of 294 amino acid residues and a mass of 31.9 kDa. Its subcellular localization is in the mitochondria. Up to 3 different isoforms have been reported for this protein. It is reported to be highly expressed in the testis, kidney, and liver. A member of the Ankyrin SOCS box (ASB) protein family, ASB9 is known to be involved with intracellular signal transduction and protein ubiquitination. Synonyms for this target antigen include ankyrin repeat and suppressor of cytokine signaling box protein 9, testis tissue sperm-binding protein Li 57p, and ankyrin repeat and SOCS box protein 9. ASB9 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some ASB9 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
