Description
Enables beta-catenin binding activity. Acts upstream of or within several processes, including myotube differentiation involved in skeletal muscle regeneration; skeletal muscle cell differentiation; and somatic stem cell population maintenance. Located in cis-Golgi network and nucleus. Is expressed in several structures, including brain; eye; head surface ectoderm; metanephros; and thymus primordium. Orthologous to human BCL9 (BCL9 transcription coactivator).
