Anti-ELK3 antibodies are used in the immunodetection of the protein ETS transcription factor ELK3. In humans, the canonical protein has a reported length of 407 amino acid residues and a mass of 44.2 kDa. Its subcellular localization is in the nucleus. It is notably expressed in many tissues, such as the bone marrow, tonsil, and appendix. A member of the ETS protein family, ELK3 is believed to be a negative regulator of transcription, but can activate transcription when coexpressed with Ras, Src or Mos. Synonyms for this target antigen include NET, SAP-2, SAP2, ETS domain-containing protein Elk-3, ELK3, ETS transcription factor, and ERP. ELK3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of ELK3 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Flow Cytometry, Immunofluorescence, and Immunohistochemistry are also common applications.
