|Application ||WB, ICC, E|
|Other Accession||NP_892017, 116734704|
|Calculated MW||61025 Da|
|Application Notes||IRF2BP2 antibody can be used for detection of IRF2BP2 by Western blot at 1 µg/mL. Antibody can also be used for immunocytochemistry starting at 2.5 µg/mL.|
|Target/Specificity||IRF2BP2; At least two isoforms of IRF2BP2 are known to exist; this antibody will detect both. This antibody is predicted to not cross-react with any FOXD4 protein family members.|
|Reconstitution & Storage||IRF2BP2 antibody can be stored at 4℃ for three months and -20℃, stable for up to one year. As with all antibodies care should be taken to avoid repeated freeze thaw cycles. Antibodies should not be exposed to prolonged high temperatures.|
|Precautions||IRF2BP2 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Acts as a transcriptional corepressor in a IRF2- dependent manner; this repression is not mediated by histone deacetylase activities. Represses the NFAT1-dependent transactivation of NFAT-responsive promoters. Acts as a coactivator of VEGFA expression in cardiac and skeletal muscle.|
|Cellular Location||Cytoplasm. Nucleus.|

IRF2BP2 Antibody: IRF2BP2, like the related protein IRF2BP1, is a co-repressor that interacts specifically with the C-terminal repression domain of Interferon Regulatory Factor 2 (IRF2). IRF2BP2 is a direct target gene of p53 and is involved in cell survival during the p53 stress response, able to impede the p53-mediated transactivation of p21 and Bax. IRF2BP2 is also a co-factor of VGLL4 and is required to induce the expression of vascular endothelial growth factor A (VEGF-A) in muscle. It is normally found in the nucleus of skeletal muscle and cardiac cells, but can be found in the cytoplasm during skeletal muscle differentiation.
