Anti-IRF2BP1 antibodies are used in the immunodetection of the protein interferon regulatory factor 2 binding protein 1. In humans, the canonical protein has a reported length of 584 amino acid residues and a mass of 61.7 kDa. Its subcellular localization is in the nucleus. It is notably widely expressed in many tissue types. A member of the IRF2BP protein family, IRF2BP1 is known to act as a transcriptional corepressor in a IRF2-dependent manner; this repression is not mediated by histone deacetylase activities. Synonyms for this target antigen include probable E3 ubiquitin-protein ligase IRF2BP1, probable RING-type E3 ubiquitin transferase IRF2BP1, and IRF-2-binding protein 1. IRF2BP1 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Some IRF2BP1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
