Anti-TENT5B antibodies are used in the immunodetection of the protein terminal nucleotidyltransferase 5B. In humans, the canonical protein has a reported length of 425 amino acid residues and a mass of 46.7 kDa. Its subcellular localization is in the nucleus and cytoplasm. A member of the TENT protein family, TENT5B is known to catalyze the transfer of one adenosine molecule from an ATP to an mRNA poly(A) tail bearing a 3'-OH terminal group in an ATP hydrolysis-dependent manner. Synonyms for this target antigen include non-canonical poly(A) polymerase FAM46B, protein FAM46B, putative nucleotidyltransferase FAM46B, and family with sequence similarity 46 member B. TENT5B gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some TENT5B antibodies may have been used in research and have associated citations. ELISA and Western Blot are common applications for these antibodies.
