Polyhomeotic distal (ph-d) encodes a stoichiometric subunit of the Polycomb repressive complex 1. The complex silences a variety of genes involved in developmental patterning, regulation of cell proliferation, differentiation and polarity. Together with its paralog ph-p, ph-d functions as a tumor suppressor gene.

Apterous (ap) encodes a transcription factor that functions in a tetramer consisting of a dimer of the product of Chi and two monomers ODF the product of ap. It contributes to the dorsal identity of wing cells, muscle development, juvenile hormone production and neuronal path finding.

Protein strawberry notch; Notch pathway component, may contribute to the specificity between lateral and inductive Notch signaling pathways in the wing disk. Required during many developmental stages including oogenesis, embryogenesis and imaginal development of the eye, wing and leg. Ebi and sno regulate EGFR-dependent Delta transcription in the developing eye, by antagonizing a repressor function of Suppressor of Hairless (Su(H)). They are required in the R-cells for normal cone cell development.

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, [...]

Homeotic protein proboscipedia; Sequence-specific transcription factor which is part of a developmental regulatory system that provides cells with specific positional identities on the anterior-posterior axis. Controls development of mouthparts, and labial and maxillary palps.

Homeotic protein labial; Labial (lab) encodes the anterio-most expressed member of the Antennapedia complex (ANT-C), one of two Hox gene complexes. Members of the ANT-C control the identity of segments that contribute to the head and the anterior thorax. The product of lab specifies the identity of the intercalary segment and also functions in the development of copper cells in the midgut.

Tondu-domain-containing Growth Inhibitor (Tgi) encodes a protein that interacts with both components of the sd-yki transcriptional complex to inhibit its activity and thus restrict tissue growth.

Transcriptional coactivator yorkie; Transcriptional coactivator which is the critical downstream regulatory target in the Hippo/SWH (Sav/Wts/Hpo) signaling pathway that plays a pivotal role in organ size control and tumor suppression by restricting proliferation and promoting apoptosis. The core of this pathway is composed of a kinase cascade wherein Hippo (Hpo), in complex with its regulatory protein Salvador (Sav), phosphorylates and activates Warts (Wts) in complex with its regulatory protein Mats, which in turn phosphorylates and inactivates the Yorkie (Yki) oncoprotein. The Hippo/ [...]

ATP-dependent helicase brm; Transcriptional regulator. Acts as a coactivator, assisting one or more dedicated transcriptional activators of ANTC and BXC homeotic gene clusters. Can counteract the repressive effect of Polycomb protein. ATPase subunit of the Brahma complex, a multiprotein complex which is the equivalent of the yeast SWI/SNF complex and acts by remodeling the chromatin by catalyzing an ATP-dependent alteration in the structure of nucleosomal DNA. This complex can both serve as a transcriptional coactivator or corepressor, depending on the context. In type II neuroblast li [...]
