Predicted to enable beta-catenin binding activity. Predicted to be involved in several processes, including canonical Wnt signaling pathway; negative regulation of transforming growth factor beta receptor signaling pathway; and positive regulation of epithelial to mesenchymal transition. Predicted to act upstream of or within skeletal muscle cell differentiation and somatic stem cell population maintenance. Predicted to be located in nucleolus and nucleoplasm. Predicted to be part of beta-catenin-TCF complex. Orthologous to human BCL9L (BCL9 like). [provided by Alliance of Genome Resources, Apr 2022]
