Function
[ABDB_DROME] Sequence-specific transcription factor which is part of a developmental regulatory system that provides cells with specific positional identities on the anterior-posterior axis. [EXD_DROME] Transcription factor which acts with the selector homeodomain proteins altering the regulation of downstream target genes such as wingless (wg), teashirt (tsh) and decapentaplegic (dpp), thus affecting segmental identity. Delimits the eye field and prevent inappropriate eye development. Required for proper localization of chordotonal organs within the peripheral nervous system.[1] [2] [3] [4] [5] [6]
