Anti-ETS variant transcription factor 7 antibodies are used for the immunodetection of the protein encoded by the ETV7 gene. In humans, the canonical protein has a reported length of 341 amino acid residues and a mass of 39 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 8 different isoforms for this protein. It is reported to be expressed in hematopoietic tissues. A member of the ETS protein family, it is known to be involved with organ morphogenesis and the regulation of transcription. Other names for this target antigen include TEL2, TELB, transcription factor ETV7, ETS-related protein Tel2, Ets transcription factor TEL-2b, and TEL-2. Gene orthologs have been identified in the mouse, chimpanzee and chicken species.
