SOX17 physically interacts with β-catenin via a conserved C-terminal motif in the SoxF subfamily, and this interaction potentiates SOX17-mediated transcriptional activation of endodermal target genes (Foxa1, Foxa2). The C-terminal motif is required both for target gene transactivation and β-catenin binding, analogous to TCF/LEF-β-catenin interactions. |
