Protocol
Available protocols: IHC Leica Bond, Immunohistochemistry (Paraffin)
Specificity / Sensitivity
BCL6 (E5I8I) Rabbit Monoclonal Antibody recognizes endogenous levels of total BCL6 protein. This antibody is predicted to detect both known isoforms of human BCL6. Non-specific, non-nuclear staining was observed in human and mouse smooth muscle. Additional non-specific staining was observed in other mouse tissues.
Species Reactivity: Human
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro319 of human BCL6 protein.
Background
Chromosomal translocations result in misregulation of the proto-oncogene in patients with B cell-derived non-Hodgkin's lymphoma (1). The gene is selectively expressed in mature B cells and encodes a nuclear phosphoprotein that belongs to the BTB/POZ zinc finger family of transcription factors (2,3). BCL6 protein can bind to target DNA sequences of Stat6 and, analogous to Stat6, modulate the expression of interleukin-4-induced genes (4). Furthermore, BCL6 restrains p53-dependent senescence, making BCL6-active tumors functionally p53-negative (5). The mitogen-activated protein kinases, Erk1 and Erk2, but not JNK, phosphorylate BCL6 at multiple sites. Phosphorylation of BCL6 at Ser333 and Ser343 results in degradation of BCL6 by the ubiquitin/proteasome pathway in B cells (6,7). In addition, BCL6 is acetylated and its transcriptional repressor function is inhibited by the transcriptional co-activator p300 (8).
