Anti-T-box transcription factor 15 antibodies are used for the immunodetection of the protein encoded by the TBX15 gene. In humans, the canonical protein has a reported length of 602 amino acid residues and a mass of 65.8 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 2 different isoforms for this protein. It is a suspected transcriptional regulator involved in the development of the skeleton of the limb, vertebral column and head. The gene encoding this protein is implicated in Cousin syndrome. Other names for this target antigen include T-box transcription factor TBX15, T-box 14, T-box 15, T-box protein 14, T-box protein 15, and TBX14. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
