Inappropriate activation of this pathway leads to developmental defects and development of certain cancers. Upon Wnt signaling, beta-catenin binds TCF/LEF transcription factors. The TCF/LEF-beta-catenin complex then recruits a variety of transcriptional coactivators to the promoter/enhancer region of Wnt-responsive genes and activates target gene transcription. In this article, we demonstrate that GRIP1-associated coactivator 63 (GAC63), a recently identified nuclear receptor (NR) coactivator, interacts with beta-catenin. The N-terminus of GAC63 is the binding site for beta-catenin, whereas a C-terminal fragment of beta-catenin including armadillo repeats 10-12 binds to GAC63. Over-expression of GAC63 enhanced the transcriptional activity of beta-catenin, and also greatly enhanced TCF/LEF-regulated reporter gene activity in a beta-catenin-dependent manner. Endogenous GAC63 was recruited to TCF/LEF-responsive enhancer elements when beta-catenin levels were induced by LiCl. In addition, reduction of endogenous GAC63 level by small interfering RNA (siRNA) inhibited TCF/LEF-mediated gene transcription. Our findings reveal a new function of GAC63 in transcriptional activation of Wnt-responsive genes."xsd:string |
