Protein escargot; Transcription factor that can both stimulate and repress transcription. Binds to the consensus DNA sequence 5'-A/GCAGGTG-3'. Regulates cell motility and adhesion during tracheal morphogenesis by stimulating transcription of the DE-cadherin gene shg at branch tips, thereby promoting tracheal tube fusion. Maintains diploidy in imaginal cells by inhibiting the transcription of genes required for endoreplication. Required for development of the genital disk and acts as an intrinsic determinant of wing cell fate. The somatic protein is required for maintenance of male germ [...]

Transcription factor btd; Buttonhead (btd) encodes a triple C(2)H(2) zinc finger protein structurally and functionally related to the human transcription factors Sp5, Sp8, and Sp9. The product of btd contributes to embryonic head segmentation, leg development, embryonic hematopoiesis, PNS formation, and maintenance of the functional heterogeneity of brain neural stem cells.

Protein wingless; Binds as a ligand to a family of frizzled seven-transmembrane receptors and acts through a cascade of genes on the nucleus. Segment polarity protein. May be a growth factor. Acts on neighboring cells to regulate at least one gene, the homeobox segmentation gene engrailed. Wg signal represses arm phosphorylation. Wg signaling operates by inactivating the sgg repression of engrailed autoactivation. Wg and Wnt2 have a role in the developing trachea and together are responsible for all dorsal trunk formation. Wg also acts in the developing epidermis. Acts as a morphogen, [...]

Dichaete (D) encodes an HMG-domain protein and member of the Sox family of transcription factors. Its roles include hindgut development, embryonic segmentation, and nervous system development.

Protein decapentaplegic; Required during oogenesis for eggshell patterning and dorsal/ventral patterning of the embryo. Acts as a morphogen during embryogenesis to pattern the dorsal/ventral axis, specifying dorsal ectoderm and amnioserosa cell fate within the dorsal half of the embryo; this activity is antagonized by binding to sog and tsg. Induces the formation of visceral mesoderm and the heart in early embryos. Required later in embryogenesis for dorsal closure and patterning of the hindgut. Also functions postembryonically as a long-range morphogen during imaginal disk development [...]

Sox21a, isoform B; Sox21a (Sox21a) encodes a Sox family transcription factor involved in the differentiation of stem cells in the midgut.

Protein hunchback; Gap class segmentation protein that controls development of head structures; Belongs to the hunchback C2H2-type zinc-finger protein family.

Spalt-related, isoform A; Spalt-related (salr) encodes a zinc finger transcriptional repressor that, together with the product of salm, mediates most dpp functions during development of the central part of the wing. It is repressed by the product of Ubx during haltere development.

Zn finger homeodomain 2 (zfh2) encodes a putative transcription factor. Its roles include specification of cell fates and promotion of apoptosis during CNS development, and proximal-distal patterning during wing and leg imaginal disc development.
