Anti-KLF3 antibodies are used in the immunodetection of the protein KLF transcription factor 3. In humans, the canonical protein has a reported length of 345 amino acid residues and a mass of 38.8 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 Krueppel C2H2-type zinc-finger protein family, KLF3 is known to bind to the CACCC box of erythroid cell-expressed genes. Post-translational modifications have been described, including sumoylation. Synonyms for this target antigen include Krueppel-like factor 3, CACCC-box-binding protein BKLF, Kruppel like factor 3, Kruppel-like factor 3 (basic), TEF-2, and BKLF. KLF3 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of KLF3 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunofluorescence is also a common application.
