BCL9L Antibody

B-cell CLL/lymphoma 9 like is a protein that in humans is encoded by the BCL9L gene. It is mapped to 11q23.3. Bcl-9 (B-cell lymphoma 9; also Protein legless homolog) is a transcriptional regulator that belongs to the Bcl-9 family of proteins. It is expressed in multiple tissues and serves to recruit Pygopus to the Wnt-pathway beta -catenin-TCF complex in the nucleus. Bcl-9 and Bcl-9-2 are considered evolutionary duplicates of Legless that perform the same task with different regulation. Human Bcl-9 is 1426 amino acids (aa) in length. It contains one phosphothreonine and three phosphoserine sites that have been identified so far, two poly-Pro regions (aa 514?517 and 970?973), and one poly-Ala segment (aa 900?903) . There is one potential alternate start site at Met27, and a variant isoform exists that shows a four aa substitution for aa 1391?1426. Over aa 1009?1328, human Bcl-9 is 96% aa identical to mouse Bcl-9.
