WebDec 10, 2024 · IRF4 is implicated in B cell malignancies, acting both as tumor suppressor and as tumor oncogene in different types of precursors and mature B cell neoplasia. Here, we summarize the complexity of IRF4 functions related to different DNA-binding affinity, multiple IRF4-specific target DNA motif, and interactions with transcriptional partners. WebMar 20, 2024 · It has been shown that IRF8 and SPI1 may contribute to BCL6 induction in antigen-engaged pre-GC-B cells, while IRF4 and PRDM1 repress BCL6 in light zone GC-B cells (16, 48). Moreover, the binding of BCL6 to its own 5′ regulatory region forms an autoregulatory circuit that limits its own expression in GC-B cells (Figure 2C) .
