Enables sequence-specific DNA binding activity. Involved in several processes, including embryonic body morphogenesis; epidermal cell fate specification; and regulation of transcription by RNA polymerase II. Located in nucleus. Expressed in several structures, including ABarpa; AIZ;
hyp5; retrovesicular ganglion neurons; and seam cell. Human ortholog(s) of this gene implicated in Parkinson's disease and autistic disorder. Is an ortholog of human EN1 (engrailed homeobox 1) and EN2 (engrailed homeobox 2).
