STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

pbHomeotic 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. (782 aa)    
Predicted Functional Partners:
Scr
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 [...]

ph-d
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.

ey
Paired box protein Pax-6; Eyeless (ey) encodes a transcription factor that is involved in eye development as part of the retinal determination gene network, and contributes to brain formation.
    
  
0.598
exd
Homeobox protein extradenticle; 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.

Dfd
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.
  
 
0.576
vg
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 [...]

Ubx
Homeotic protein ultrabithorax; Sequence-specific transcription factor which is part of a developmental regulatory system that provides cells with specific positional identities on the anterior-posterior axis. Binds the consensus region 5'-TTAAT[GT][GA]-3'. This homeotic protein controls development of the cells in the posterior thoracic and first abdominal segments. It activates the synthesis of the decapentaplegic (DPP) growth factor; Belongs to the Antp homeobox family.
  
 
0.553
Antp
Homeotic protein antennapedia; Antennapedia (Antp) is the distal-most member of the Antennapedia complex; one of two Hox gene complexes. Antp encodes a sequence-specific homeodomain transcription factor, which is part of a developmental regulatory system that specifies segmental identity in the pro- and mesothorax. In adults Antp loss of function is associated with a transformation of leg into antenna while ectopic expression in the head is associated with antenna to leg and eye to wing transformations.
  
 
0.548
abd-A
Homeobox protein abdominal-A; Sequence-specific transcription factor which is part of a developmental regulatory system that provides cells with specific positional identities on the anterior-posterior axis. Required for segmental identity of the second through eighth abdominal segments. Once a pattern of abd-A expression is turned on in a given parasegment, it remains on the more posterior parasegment, so that the complex pattern of expression is built up in the successive parasegments. Appears to repress expression of Ubx whenever they appear in the same cell, but abd-A is repressed [...]

lab
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.
