Bcl-9 (B-cell CLL/lymphoma 9 protein) is a nuclear protein encoded by the human gene BCL9. Bcl-9 belongs to the BCL9 family and is involved in the Wnt signaling pathway. The Wnt signaling pathway controls numerous cell fates during animal development. A malfunction in Wnt signaling activity can lead to cancer in many human tissues. A key effector of the canonical Wnt pathway is b-catenin (or Drosophila Armadillo), a highly unstable phosphorylated protein that shuttles rapidly between nucleus and cytoplasm. A nuclear complex, consisting of Bcl-9/Bcl-9L, b-catenin and other proteins, activates transcription of several Wnt target genes, including FGF-20, WISP-1, Myc, and Glucagon. |
