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.

Protein vestigial; Involved in determining which thoracic imaginal disk cells will form wings and halteres, perhaps by interacting with other nuclear regulatory proteins. When in combination with scalloped (sd), it acts as a transcriptional activation complex that regulates gene expression in the wing. Binding to sd switches the DNA target selectivity of sd. Required and sufficient for cell proliferation at the dorsal/ventral (D/V) boundary of the wing imaginal disk. Also required for cell proliferation in the wing imaginal disk, mediated via activation of E2f. By interacting with Dhfr [...]

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.

RE01453p.

BcDNA.GH02439.

Uncharacterized protein, isoform B; Potassium channel regulator activity. It is involved in the biological process described with: muscle contraction; regulation of muscle contraction; regulation of potassium ion transport.

Homeotic protein Sex combs reduced; 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 the segmental transformation of the first to the second thoracic segment (prothorax to mesothorax) and of the labial palps into maxillary palps. In embryo, required for fusion of labial lobes and development of the T1 denticle belt. In adult, expression in the head is necessary for proper development of the labium. In the first thoracic segment of the adult, required [...]

Homeotic protein deformed; Sequence-specific transcription factor which is part of a developmental regulatory system that provides cells with specific positional identities on the anterior-posterior axis. Homeotic protein controlling Drosophila head development. Transcriptional activator of the apoptotic activator protein rpr in cells at the maxillary/mandibular boundary; Belongs to the Antp homeobox family. Deformed subfamily.

Homeobox protein homothorax; All isoforms are required for patterning of the embryonic cuticle. Acts with exd to delimit the eye field and prevent inappropriate eye development. Isoforms that carry the homeodomain are required for proper localization of chordotonal organs within the peripheral nervous system and antennal identity; required to activate antennal-specific genes, such as sal and to repress the leg-like expression of dac. Necessary for the nuclear localization of the essential HOX cofactor, extradenticle (exd). Both necessary and sufficient for inner photoreceptors to adopt [...]
