Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Acts upstream of or within several processes, including animal organ development; digestive tract development; and pharyngeal system development. Predicted to be active in nucleus. Is expressed in several structures, including branchial arch; genitourinary system; gut; heart; and thymus. Orthologous to human NKX2-6 (NK2 homeobox 6).
