Anti-ILF3 antibodies are used in the immunodetection of the protein interleukin enhancer binding factor 3. In humans, the canonical protein has a reported length of 894 amino acid residues and a mass of 95.3 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 7 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. ILF3 is reported to be a RNA-binding protein that plays an essential role in the biogenesis of circular RNAs (circRNAs) which are produced by back-splicing circularization of pre-mRNAs. Synonyms for this target antigen include DRBF, DRBP76, MMP4, MPHOSPH4, MPP4, MPP4110, NF-AT-90, and CBTF. ILF3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. Over 50 citations in the literature describe the use of ILF3 antibodies in research. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
