Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Acts upstream of or within several processes, including digestive system development; negative regulation of Wnt signaling pathway; and spleen development. Predicted to be active in nucleus. Is expressed in several structures, including alimentary system; branchial arch; central nervous system; limb bud; and sensory organ. Orthologous to human BARX1 (BARX homeobox 1).
