Anti-TERB2 antibodies are used in the immunodetection of the protein telomere repeat binding bouquet formation protein 2. In humans, the canonical protein has a reported length of 220 amino acid residues and a mass of 25.3 kDa. Its subcellular localization is in the nucleus and chromosomes. A member of the TERB2 protein family, TERB2 is known to be involved with spermatogenesis. The TERB2 gene has been associated with the disease, Spermatogenic failure. Synonyms for this target antigen include telomere repeats-binding bouquet formation protein 2. TERB2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
