Abstract: SUMMARY The BCL6 transcriptional repressor is required for development of germinal center (GC) B-cells and diffuse large B-cell lymphomas (DLBCL). Although BCL6 can recruit multiple corepressors, its transcriptional repression mechanism of action in normal and malignant B-cells is unknown. We find that in B-cells, BCL6 mostly functions through two independent mechanisms that are collectively essential to GC formation and DLBCL, both mediated through its N-terminal BTB domain. These are: i) formation of a uniq…
