Detection of Human Bcl9‑2 by Western Blot.
Western blot shows lysates of A172 human glioblastoma cell line and MCF‑7 human breast cancer cell line. PVDF membrane was probed with 1 µg/mL of Human Bcl9‑2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4967) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Bcl9‑2 at approximately 190 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Bcl9-2 (B-cell lymphoma 9-like protein; also Bcl9L and B9L) is a 200-220 kDa transcriptional regulator that belongs to the Bcl9 family of proteins. It is expressed in multiple tissues, particularly breast, and serves to recruit Pygopus to the Wnt-pathway beta -catenin-TCF complex in the nucleus. Bcl9-2 and Bcl9 are considered evolutionary duplicates of Legless that perform the same task with different regulation. Human Bcl9-2 is 1499 amino acids (aa) in length. It contains two Pro-rich regions (aa 280-493 and 891-1378). There are four potential alternate start sites at Met879, Met1000, Met708 and Met472. The last two start sites are accompanied by a deletion of aa 1241-1286, and a 62 aa substitution for the C-terminal 167 aa, respectively. Over aa 38-206, human Bcl9-2 is 94% aa identical to mouse Bcl9-2. Bcl9-2 has been identified as a phosphoprotein in several human cancer cell lines and mouse liver.
