Anti-TTLL2 antibodies are used in the immunodetection of the protein tubulin tyrosine ligase like 2. In humans, the canonical protein has a reported length of 592 amino acid residues and a mass of 67.3 kDa. It is notably expressed in the testis. A member of the Tubulin--tyrosine ligase protein family, TTLL2 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 (By similarity). Synonyms for this target antigen include testis-specific protein NYD-TSPG, tubulin tyrosine ligase-like family, member 2, tubulin--tyrosine ligase-like protein 2, and probable tubulin polyglutamylase TTLL2. TTLL2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. ELISA is a widely used application for the TTLL2 antibodies listed below. In addition, Immunohistochemistry is also a common application.
