[https://www.uniprot.org/uniprot/EVE_DROME EVE_DROME] May play a role in determining neuronal identity. May be directly involved in specifying identity of individual neurons. Pair-rule protein required for segmentation; involved in transforming the broad, spatial, aperiodic expression patterns of the gap genes into a system of precise periodic expression patterns of the pair-rule and segmentary polarity genes.

even-skipped is a homeobox gene important in controlling segment patterning in the embryonic fruit fly. Its homeobox encodes a DNA binding domain which binds with similar affinities to two DNA consensus sequences, one AT-rich, the other GC-rich. We describe a crystallographic analysis of the Even-skipped homeodomain complexed to an AT-rich oligonucleotide at 2.0 A resolution. The structure reveals a novel arrangement of two homeodomains bound to one 10 bp DNA sequence in a tandem fashion. This arrangement suggests a mechanism for the homeoproteins' regulatory specificity. In addition, the functionally important residue Gln50 is observed in multiple conformations making direct and water-mediated hydrogen bonds with the DNA bases.
