Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

The Bcl6 protein also known as B-cell lymphoma 6 is a transcriptional repressor important for the germinal center formation in B-cells. It has a molecular weight of approximately 95 kDa. Bcl6 is expressed mainly in B-cells T-cells and certain subsets of dendritic cells. It functions by binding to target DNA sequences where it represses the expression of specific genes leading to controlled cell proliferation differentiation and apoptosis. Researchers often study Bcl6 through the use of monoclonal antibodies particularly in immunohistochemistry (IHC).
Biological function summary

Bcl6 plays essential roles in immune response regulation and lymphocyte development. In germinal centers Bcl6 influences the process of somatic hypermutation and class switch recombination in B-cells which is a part of generating antibody diversity. It operates as a central player in a multiprotein complex that includes corepressors such as SMRT and NCoR which facilitate the repression of its target genes. This regulatory action helps maintain the precise balance of immune cell functions.

Pathways

Bcl6 integrates into the B-cell receptor (BCR) signaling and the JAK-STAT pathway. It interacts with molecules like STAT1 and STAT3 positively influencing the survival and proliferation of B-cells. In these pathways Bcl6's activity modulates the transcriptional landscape that determines cell fate decisions affecting cellular processes such as proliferation and survival in response to external cues.

Bcl6 is relevant to B cell lymphomas specifically diffuse large B-cell lymphoma (DLBCL) where it is often overexpressed contributing to malignancy by preventing cell death. This pathology frequently involves chromosomal translocations that juxtapose the Bcl6 gene with immunoglobulin genes. The relationship between Bcl6 and other proteins like Bcl2 is noteworthy in this context as Bcl2 inhibits apoptosis further contributing to cancer progression. Mutations and dysregulated expression of Bcl6 have also shown links to autoimmune diseases where its role in cell differentiation and survival may lead to aberrant immune responses.

Target data

Transcriptional repressor mainly required for germinal center (GC) formation and antibody affinity maturation which has different mechanisms of action specific to the lineage and biological functions. Forms complexes with different corepressors and histone deacetylases to repress the transcriptional expression of different subsets of target genes. Represses its target genes by binding directly to the DNA sequence 5'-TTCCTAGAA-3' (BCL6-binding site) or indirectly by repressing the transcriptional activity of transcription factors. In GC B-cells, represses genes that function in differentiation, inflammation, apoptosis and cell cycle control, also autoregulates its transcriptional expression and up-regulates, indirectly, the expression of some genes important for GC reactions, such as AICDA, through the repression of microRNAs expression, like miR155. An important function is to allow GC B-cells to proliferate very rapidly in response to T-cell dependent antigens and tolerate the physiological DNA breaks required for immunglobulin class switch recombination and somatic hypermutation without inducing a p53/TP53-dependent apoptotic response. In follicular helper CD4(+) T-cells (T(FH) cells), promotes the expression of T(FH)-related genes but inhibits the differentiation of T(H)1, T(H)2 and T(H)17 cells. Also required for the establishment and maintenance of immunological memory for both T- and B-cells. Suppresses macrophage proliferation through competition with STAT5 for STAT-binding motifs binding on certain target genes, such as CCL2 and CCND2. In response to genotoxic stress, controls cell cycle arrest in GC B-cells in both p53/TP53-dependedent and -independent manners. Besides, also controls neurogenesis through the alteration of the composition of NOTCH-dependent transcriptional complexes at selective NOTCH targets, such as HES5, including the recruitment of the deacetylase SIRT1 and resulting in an epigenetic silencing leading to neuronal differentiation.
