Anti-TRPT1 antibodies are used in the immunodetection of the protein tRNA phosphotransferase 1. In humans, the canonical protein has a reported length of 253 amino acid residues and a mass of 27.7 kDa. Up to 4 different isoforms have been reported for this protein. It is widely expressed across many tissue types. A member of the KptA/TPT1 protein family, TRPT1 is known to catalyze the last step of tRNA splicing, the transfer of the splice junction 2'-phosphate from ligated tRNA to NAD to produce ADP-ribose 1''-2'' cyclic phosphate. Synonyms for this target antigen include tRNA 2'-phosphotransferase 1 and tRNA splicing 2' phosphotransferase 1. TRPT1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some TRPT1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
