Anti-ETV3 antibodies are used in the immunodetection of the protein ETS variant transcription factor 3. In humans, the canonical protein has a reported length of 512 amino acid residues and a mass of 57 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the ETS protein family, ETV3 is reported to be a transcriptional repressor that contribute to growth arrest during terminal macrophage differentiation by repressing target genes involved in Ras-dependent proliferation. Synonyms for this target antigen include PE-1, PE1, ETS translocation variant 3, ETS domain transcriptional repressor PE1, ets variant gene 3, ETS family transcriptional repressor, and METS. ETV3 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some ETV3 antibodies may have been used in research and have associated citations. Immunocytochemistry is a widely used application for these antibodies. Western Blot, Immunofluorescence, and Immunohistochemistry are also common applications.
