Anti-TTC29 antibodies are used in the immunodetection of the protein tetratricopeptide repeat domain 29. In humans, the canonical protein has a reported length of 475 amino acid residues and a mass of 55.1 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in spermatozoa. TTC29 is reported to be an axonemal protein, which is implicated in axonemal and/or peri-axonemal structures assembly and regulates flagella assembly and beating and therefore sperm motility. The TTC29 gene has been associated with the disease, Spermatogenic failure. Synonyms for this target antigen include TPR repeat protein 29, testicular secretory protein Li 62, testis development protein NYD-SP14, and tetratricopeptide repeat protein 29. TTC29 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. These TTC29 antibodies are widely used in Immunohistochemistry experiments, among other applications.
