Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables beta-catenin binding activity. Acts upstream of or within several processes, including myotube differentiation involved in skeletal muscle regeneration; positive regulation of transcription by RNA polymerase II; and skeletal muscle cell differentiation. Located in cis-Golgi network; nucleus; and sarcoplasm. Is expressed in several structures, including brain; eye; head surface ectoderm; metanephros; and thymus primordium. Orthologous to human BCL9 (BCL9 transcription coactivator).
