Summary: Enables DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in several processes, including nervous system development; regionalization; and regulation of gene expression. Located in nucleus. Is expressed in several structures, including anterior-posterior subdivision of organism; compartment; larval imaginal tissue; larval neurons; and neuroblasts. Human ortholog(s) of this gene implicated in Parkinson's disease and autistic disorder. Orthologous to human EN1 (engrailed homeobox 1) and EN2 (engrailed homeobox 2).

En forms a complex with Nejire (Nej), the Drosophila ortholog of histone acetyltransferase CBP/p300, and directs Nej to this cis-regulatory region where Nej functions as the co-activator for dpp expression.
Title: Engrailed acts with Nejire to control decapentaplegic expression in the Drosophila ovarian stem cell niche.
Data indicate there is redundancy in both regulatory DNA and protein function in invected (inv) and engrailed (en) genes.
Title: Co-regulation of invected and engrailed by a complex array of regulatory sequences in Drosophila.
