Enables DNA-binding transcription activator activity, RNA polymerase II-specific and R-SMAD binding activity. Involved in several processes, including melanocyte migration; positive regulation of cell differentiation; and regulation of transcription by RNA polymerase II. Acts upstream of or within several processes, including nervous system development; neural crest cell migration; and positive regulation of signal transduction. Located in nucleus. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; limb; and sensory organ. Used to study Mowat-Wilson syndrome and T-cell adult acute lymphocytic leukemia. Human ortholog(s) of this gene implicated in Hirschsprung's disease and Mowat-Wilson syndrome. Orthologous to human ZEB2 (zinc finger E-box binding homeobox 2). [provided by Alliance of Genome Resources, Apr 2022]
