Anti-IRF2BP2 antibodies are used in the immunodetection of the protein interferon regulatory factor 2 binding protein 2. In humans, the canonical protein has a reported length of 587 amino acid residues and a mass of 61 kDa. Its subcellular localization is in the nucleus and cytoplasm. Alternative splicing is reported to yield 3 different isoforms for this protein. A member of a the IRF2BP protein family, IRF2BP2 is known to act as a transcriptional corepressor in a IRF2-dependent manner; this repression is not mediated by histone deacetylase activities. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include IRF-2-binding protein 2.
