Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables beta-catenin binding activity. Involved in several processes, including negative regulation of canonical Wnt signaling pathway; negative regulation of smooth muscle cell proliferation; and negative regulation of transcription initiation by RNA polymerase II. Acts upstream of or within anterior/posterior pattern specification; branching involved in ureteric bud morphogenesis; and negative regulation of Wnt signaling pathway. Part of beta-catenin-ICAT complex. Is expressed in several structures, including alimentary system; brain; genitourinary system; immune system; and respiratory system. Orthologous to human CTNNBIP1 (catenin beta interacting protein 1).
