Predicted to enable armadillo repeat domain binding activity and beta-catenin binding activity. Predicted to be involved in several processes, including negative regulation of cell population proliferation; positive regulation of cell differentiation; and regulation of transcription, DNA-templated. Predicted to act upstream of or within anterior/posterior pattern specification; branching involved in ureteric bud morphogenesis; and negative regulation of transcription by RNA polymerase II. Predicted to be located in cytoplasm. Predicted to be part of beta-catenin destruction complex. Predicted to be active in cytosol and nucleus. Orthologous to human CTNNBIP1 (catenin beta interacting protein 1). [provided by Alliance of Genome Resources, Apr 2022]
