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

ocHomeotic protein ocelliless; Transcriptional regulator involved in pattern formation and cell determination in the embryonic CNS and larval imaginal disks. Also later in development to coordinate the expression of regulatory and structural genes required for photoreceptor cell fate in the ocelli. Has a dual role in the terminal differentiation of subtypes of photoreceptors by regulating rhodopsin (rh) expression: essential for establishing the expression of rh genes in the pale subset of ommatidia as well as repressing Rh6 in outer photoreceptors. Belongs to the paired homeobox family. (664 aa)    
Predicted Functional Partners:
Rh5
Rhodopsin 5 (Rh5) encodes a visual GPCR opsin that covalently binds the chromophore retinal. A photon of light stimulates the isomerization of retinal resulting in a conformational change in the product of Rh5 and signal activation. Its peak sensitivity is in the blue and it is expressed in a subclass of R8 photoreceptors; Belongs to the G-protein coupled receptor 1 family. Opsin subfamily.
   
  
 0.852
Rh6
Opsin Rh6; Visual pigments are the light-absorbing molecules that mediate vision. They consist of an apoprotein, opsin, covalently linked to cis-retinal.
   
  
 0.852
btd
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.
   
 
 0.847
Rh3
Rhodopsin 3 (Rh3) encodes a Rhodopsin GPCR protein that responds to UV light and activates the phototransduction cascade that leads to photoreceptor depolarization. Rh3 is expressed in R7 photoreceptors in a stochastic manner: 35% of R7 photoreceptors express Rh3 while the remaining 65% express another UV-sensitive Rhodopsin encoded by Rh4.
   
 
 0.827
Optix
Optix (Optix) encodes a homeobox containing DNA binding protein and a member of the SIX class of proteins. It functions as a repressor via interaction with the transcriptional co-repressor encoded by gro. It is involved in eye formation and morphogenetic furrow movement.
   
 
 0.751
sv
Shaven, isoform A; Shaven (sv) encodes a transcription factor and a member of the paired box family of genes. It is primarily involved in the terminal differentiation of specific cell types during the development of a variety of sensory organs, including the bristles and the eye.
   
  
 0.713
Rh4
Opsin Rh4; Visual pigments are the light-absorbing molecules that mediate vision. They consist of an apoprotein, opsin, covalently linked to cis-retinal.
   
  
 0.707
hb
Protein hunchback; Gap class segmentation protein that controls development of head structures; Belongs to the hunchback C2H2-type zinc-finger protein family.
    
 
 0.695
fkh
Fork head (fkh) encodes a winged-helix nuclear transcription factor most studied for its role in salivary gland formation, where it is required for salivary gland viability, invagination, and maintaining expression of other early-expressed salivary gland transcription factors. It works with the product of sage to activate expression of salivary gland specific gene products, such as secreted proteins and their modifying enzymes.
   
 
 0.694
dve
Defective proventriculus (dve) encodes a transcriptional repressor that binds to the K50 site. It is involved in developmental patterning, cell-type specification, and functional differentiation.
