Role of a BCL9-related beta-catenin-binding protein, B9L, in tumorigenesis induced by aberrant activation of Wnt signaling.

Wnt signaling plays a crucial role in a number of developmental processes and in tumorigenesis. beta-Catenin is stabilized by Wnt signaling and associates with the TCF/LEF family of transcription factors, thereby activating transcription of Wnt target genes. Constitutive activation of beta-catenin-TCF-mediated transcription resulting from mutations in adenomatous polyposis coli (APC), beta-catenin, or Axin is believed to be a critical step ... [more]

Additional Notes

  • Transactivation potential of the beta-catenin-TCF complex is enhanced by its interaction with a BCL9-like protein, B9L, in addition to BCL9

An interaction is inferred between proteins in vitro. This can include proteins in recombinant form or proteins isolated directly from cells with recombinant or purified bait. For example, GST pull-down assays where a GST-tagged protein is first isolated and then used to fish interactors from cell lysates are considered reconstituted complexes (e.g. PUBMED: 14657240, Fig. 4A or PUBMED: 14761940, Fig. 5). This can also include gel-shifts, surface plasmon resonance, isothermal titration calorimetry (ITC) and bio-layer interferometry (BLI) experiments. The bait-hit directionality may not be clear for 2 interacting proteins. In these cases the directionality is up to the discretion of the curator.
