CC -!- FUNCTION: Transcriptional repressor mainly required for germinal center
CC (GC) formation and antibody affinity maturation which has different
CC mechanisms of action specific to the lineage and biological functions.
CC Forms complexes with different corepressors and histone deacetylases to
CC repress the transcriptional expression of different subsets of target
CC genes. Represses its target genes by binding directly to the DNA
CC sequence 5'-TTCCTAGAA-3' (BCL6-binding site) or indirectly by
CC repressing the transcriptional activity of transcription factors. In GC
CC B-cells, represses genes that function in differentiation,
CC inflammation, apoptosis and cell cycle control, also autoregulates its
CC transcriptional expression and up-regulates, indirectly, the expression
CC of some genes important for GC reactions, such as AICDA, through the
CC repression of microRNAs expression, like miR155. An important function
CC is to allow GC B-cells to proliferate very rapidly in response to T-
CC cell dependent antigens and tolerate the physiological DNA breaks
CC required for immunglobulin class switch recombination and somatic
CC hypermutation without inducing a p53/TP53-dependent apoptotic response.
CC In follicular helper CD4(+) T-cells (T(FH) cells), promotes the
CC expression of T(FH)-related genes but inhibits the differentiation of
CC T(H)1, T(H)2 and T(H)17 cells. Also required for the establishment and
CC maintenance of immunological memory for both T- and B-cells. Suppresses
CC macrophage proliferation through competition with STAT5 for STAT-
CC binding motifs binding on certain target genes, such as CCL2 and CCND2.
CC In response to genotoxic stress, controls cell cycle arrest in GC B-
CC cells in both p53/TP53-dependedent and -independent manners. Besides,
CC also controls neurogenesis through the alteration of the composition of
CC NOTCH-dependent transcriptional complexes at selective NOTCH targets,
CC such as HES5, including the recruitment of the deacetylase SIRT1 and
CC resulting in an epigenetic silencing leading to neuronal
CC differentiation. {ECO:0000269|PubMed:10981963,

CC -!- SUBUNIT: Homodimer. Interacts (via BTB domain) with the corepressors
CC BCOR, NCOR1 and SMRT/NCOR2; the interactions are direct. Forms
CC preferably ternary complexes with BCOR and SMRT/NCOR2 on target gene
CC promoters but, on enhancer elements, interacts with SMRT/NCOR2 and
CC HDAC3 to repress proximal gene expression. Interacts with histone
CC deacetylases HDAC2, HDAC5 and HDAC9 (via the catalytic domain).
CC Interacts with ZBTB7 and BCL6B. Interacts with SCF(FBXO11) complex; the
CC interaction is independent of phosphorylation and promotes
CC ubiquitination. Interacts (when phosphorylated) with PIN1; the
CC interaction is required for BCL6 degradation upon genotoxic stress.
CC Interacts with ZBTB17; inhibits ZBTB17 transcriptional activity.
CC Interacts with CTBP1, autoinhibits its transcriptional expression.
CC Interacts with NOTCH1 NCID and SIRT1; leads to a epigenetic repression
CC of selective NOTCH1-target genes. Interacts (nor via BTB domain neither
CC acetylated) with the NuRD complex components CHD4, HDAC1, MBD3 and
CC MTA3; the interaction with MTA3 inhibits BCL6 acetylation and is
CC required for BCL6 transpriptional repression.

CC primary immature dendritic cells. {ECO:0000269|PubMed:10981963,

CC -!- INDUCTION: Down-regulated during maturation of dendritic cells by
CC selective stimuli such as bacterial lipopolysaccharides (LPS), CD40LG
CC and zymosan. Protein levels decreases upon genotoxic stress in a
CC dose- and time-dependent way. {ECO:0000269|PubMed:16455075,
CC ECO:0000269|PubMed:17828269}.
CC -!- DOMAIN: The BTB domain mediates homodimerization. Its dimer interface
CC mediates peptide binding such as to corepressors BCOR and NCOR2
CC (PubMed:18212045). Interaction with corepressors through the BTB domain
CC is needed to facilitate the rapid proliferation and survival of GC B-
CC cells but is not involved in the T(FH) formation and BCL6-mediated
CC suppression of T(H)2 and T(H)17 differentiationrequired for GC
CC formation (By similarity). {ECO:0000250, ECO:0000269|PubMed:18212045}.
CC -!- PTM: Phosphorylated by MAPK1 in response to antigen receptor activation
CC at Ser-333 and Ser-343. Phosphorylated by ATM in response to genotoxic
CC stress. Phosphorylation induces its degradation by ubiquitin/proteasome
CC pathway. {ECO:0000269|PubMed:17828269, ECO:0000269|PubMed:22113614,
CC ECO:0000269|PubMed:9649500}.
CC -!- PTM: Polyubiquitinated (PubMed:9649500, PubMed:22113614,
CC PubMed:30190310). Polyubiquitinated by SCF(FBXO11), leading to its
CC degradation by the proteasome (PubMed:22113614). Ubiquitinated by the
CC SCF(FBXL17) complex, leading to its degradation by the proteasome:
CC ubiquitination by the SCF(FBXL17) complex takes place when aberrant BTB
CC domain dimers are formed (PubMed:30190310).

CC -!- PTM: Acetylated at Lys-379 by EP300 which inhibits the interaction with
CC NuRD complex and the transcriptional repressor function. Deacetylated
CC by HDAC- and SIR2-dependent pathways. {ECO:0000269|PubMed:12402037,

CC -!- DISEASE: Note=Chromosomal aberrations involving BCL6 are a cause of B-
CC cell non-Hodgkin lymphomas (B-cell NHL), including diffuse large B-cell
CC lymphoma and follicular lymphoma. Approximately 40% of diffuse large B-
CC cell lymphomas and 5 to 10% of follicular lymphomas are associated with
CC chromosomal translocations that deregulate expression of BCL6 by
CC juxtaposing heterologous promoters to the BCL6 coding domain
CC (PubMed:10469447, PubMed:10753856, PubMed:12414651, PubMed:11821949).
CC Translocation t(3;14)(q27;q32). Translocation t(3;22)(q27;q11) with
CC immunoglobulin gene regions (PubMed:11821949). Translocation
CC t(3;7)(q27;p12) with IKZF1 gene 5'non-coding region (PubMed:10753856).
