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.\nSpecies Reactivity: Human\n\u003cb\u003eSource \/ Purification\u003c\/b\u003e\nMonoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro319 of human BCL6 protein.\n\u003cb\u003eBackground\u003c\/b\u003e\nChromosomal 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).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nB cell CLL\/lymphoma 6; B-cell CLL\/lymphoma 6; B-cell lymphoma 5 protein; B-cell lymphoma 6 protein; B-cell lymphoma 6 protein transcript; BCL-5; BCL-6; BCL5; BCL6; BCL6 transcription repressor; BCL6A; cys-his2 zinc finger transcription factor; LAZ3; lymphoma-associated zinc finger gene on chromosome 3; Protein LAZ-3; ZBTB27; Zinc finger and BTB domain-containing protein 27; Zinc finger protein 51; zinc finger transcription factor BCL6S; ZNF51\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 90\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46800289104041,"sku":"89369T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-89369t","provider":"Iright","version":"1.0","type":"link"}
