Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in cell differentiation and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including animal organ morphogenesis; hematopoietic or lymphoid organ development; and post-embryonic digestive tract morphogenesis. Predicted to be active in nucleus. Orthologous to human NKX2-3 (NK2 homeobox 3). [provided by Alliance of Genome Resources, Apr 2022]
