Anti-TUG1 antibodies are used in the immunodetection of the protein taurine up-regulated 1. In humans, the canonical protein has a reported length of 153 amino acid residues and a mass of 16 kDa. Its subcellular localization is in the nucleus, mitochondria, and cytoplasm. It is ubiquitously expressed across many tissue types. Synonyms for this target antigen include NCRNA00080, TI-227H, taurine upregulated gene 1, and LINC00080. TUG1 gene orthologs have been reported in the mouse, rat and bovine species.
