Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding His138 of human BCL9 protein. Antibodies are purified by protein A and peptide affinity chromatography.
B-cell CLL/lymphoma 9 protein (BCL9) is a widely conserved adaptor protein that functions as a transcriptional co-activator in the canonical Wnt signaling pathway (1,2). BCL9 is a core component of a nuclear protein complex (BCL9, LEF/TCF, β-catenin and PYGO) that regulates the transcription of Wnt-dependent target genes (3). Research studies show that disrupting the interaction between BCL9 and β-catenin suppresses oncogenic Wnt signaling, suggesting a potential avenue for therapeutic intervention in Wnt-mediated cancers (4). BCL9 promotes association of PYGO with the tail of histone H3 that has been methylated at lysine 4 (H3K4me), suggesting a specific chromatin remodeling function for BCL9 in the Wnt signaling pathway (5). Research studies in colon epithelium and adenocarcinomas suggest that BCL9 is required to mediate Wnt-dependent stem cell behaviors, such as epithelial-mesenchymal transition (6). Crystallography studies revealed that BCL9 contains a β-catenin binding site that is distinct from the majority of known β-catenin binding partners, making it an attractive target for therapeutic drug development (7).
