Anti-TTLL9 antibodies are used in the immunodetection of the protein tubulin tyrosine ligase like 9. In humans, the canonical protein has a reported length of 439 amino acid residues and a mass of 51.5 kDa. Its subcellular localization is in the cytoplasm. Up to 3 different isoforms have been reported for this protein. A member of the Tubulin--tyrosine ligase protein family, TTLL9 is a suspected tubulin polyglutamylase that generates side chains of glutamate on the gamma-carboxyl group of specific glutamate residues within the C-terminal tail of target proteins. Synonyms for this target antigen include tubulin tyrosine ligase-like family, member 9, tubulin--tyrosine ligase-like protein 9, and probable tubulin polyglutamylase TTLL9. TTLL9 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. ELISA is a widely used application for the TTLL9 antibodies listed below. In addition, Immunohistochemistry is also a common application.
