Synthesis pass · prose summary of the discoveries below

IRF2BP2 is a nuclear transcriptional co-repressor that uses its RING domain to recognize a conserved RxSVI motif in diverse partner proteins—including IRF2, VGLL4, ZBTB16, and NFAT1—thereby modulating inflammatory, metabolic, and differentiation programs across multiple tissues (PMID:39616187, PMID:28716987). In macrophages and microglia, IRF2BP2 activates KLF2 expression through MEF2 and suppresses NF-κB, STAT1, and AP-1/ATF7-JDP2 inflammatory signaling; its loss causes exaggerated inflammatory responses, impaired cholesterol efflux, and worsened stroke outcomes (PMID:26195219, PMID:28769762, PMID:38801077). IRF2BP2 directly represses metabolic target genes such as ATF3 in hepatocytes and LIPE in adipocytes, and its hepatocyte- or adipocyte-specific deletion exacerbates hepatic steatosis or adipose inflammation, respectively (PMID:31529495, PMID:39752494). In hematopoiesis, IRF2BP2 is essential for fetal erythropoiesis and megakaryocytic differentiation, cooperates with TRIM28/DNMT1 to silence transposable elements in AML, and is required for T-ALL cell survival through super-enhancer-driven regulation of MYC/E2F pathways (PMID:35865523, PMID:39616187, PMID:39454110).

2008 IRF2BP2 was identified as a direct transcriptional target of p53. Upregulation of IRF2BP2 after actinomycin D treatment is p53-dependent. Overexpressed IRF2BP2 impedes p53-mediated transactivation of p21 and Bax genes. Knockdown of IRF2BP2 leads to upregulation of p21 and faster induction of apoptosis after doxorubicin or actinomycin D treatment, indicating IRF2BP2 modulates cell survival decisions during p53 stress response.

2015 IRF2BP2 is required for MEF2-dependent activation of KLF2 (Krüppel-like factor 2) in macrophages. Promoter studies revealed this dependence. IRF2BP2-deficient macrophages have markedly reduced KLF2 expression, impaired cholesterol efflux due to inability to activate ABCA1, and increased M1 inflammatory activation.
