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

salmHomeotic protein spalt-major; Spalt major (salm) encodes a zinc finger transcriptional repressor. It mediates most dpp functions during development of the central part of the wing through regulation of the products of kni and ara. The product of salm is required for cell specification during the development of the nervous system, muscle, eye or trachea. (1365 aa)    
Predicted Functional Partners:
salr
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.

hth
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 [...]

Caf1-55
Probable histone-binding protein Caf1; Core histone-binding subunit that may target chromatin assembly factors, chromatin remodeling factors and histone deacetylases to their histone substrates in a manner that is regulated by nucleosomal DNA. Component of several complexes which regulate chromatin metabolism. These include the chromatin assembly factor 1 (CAF-1) complex, which is required for chromatin assembly following DNA replication and DNA repair; the nucleosome remodeling and deacetylase complex (the NuRD complex), which promotes transcriptional repression by histone deacetylati [...]

bi
Optomotor-blind protein; Bifid (bi) encodes a T-box transcription factor that controls cell proliferation, viability and cell migration. It contributes to the development of several tissues such as brain, eyes and wings. In wing development it is activated by the product of dpp and to a lesser extent by Wg signaling.

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 [...]

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.

vvl
POU domain protein CF1A; Binds to a DNA sequence element required for the expression of the dopa decarboxylase gene (Ddc) in specific dopaminergic neurons. Could also play an early role in specific ectodermal cells, and a subsequent role in the embryonic nervous system. Belongs to the POU transcription factor family. Class-3 subfamily.

brk
Putative transcription factor; Brinker (brk) encodes a transcriptional repressor that plays important roles in the development of many tissues, including most imaginal discs, where its expression is negatively regulated by Dpp signaling.
   
  
 0.659
kni
Zygotic gap protein knirps; Transcriptional repressor. Binds to multiple sites in the eve stripe 3 enhancer element. Plays an essential role in the segmentation process both by refining the expression patterns of gap genes and by establishing pair-rules stripes of gene expression.
   
 
 0.632
dpp
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 [...]
