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

Rh2Rhodopsin 2 (Rh2) encodes a light sensitive GPCR Rhodopsin protein that activates the phototransduction cascade and leads to photoreceptor depolarization. It responds to a broad spectrum of wavelengths of light and is exclusively expressed in the ocelli, which are likely involved in horizon detection. (381 aa)    
Predicted Functional Partners:
Arr2
Phosrestin-1; Arrestin 2 (Arr2) encodes a protein involved in rhodopsin inactivation that contributes to photoreceptor maintenance and smell and sound perception.
   
 
 0.752
inaD
Inactivation-no-after-potential D protein; Involved in the negative feedback regulation of the light- activated signaling cascade in photoreceptors through a calcium- mediated process. Interacts with tetrapeptide ligand located in C- terminal sequence of 3 key components of the visual cascade, tethering them and forming a macromolecular signaling phototransduction complex.
   
 
 0.740
Gbeta76C
Guanine nucleotide-binding protein subunit beta-2; G protein beta-subunit 76C (Gbeta76C) encodes a protein that forms a Gbeta-gamma complex that is anchored to the plasma membrane via lipid modification of the gamma-subunit. The Gbeta-gamma complex plays an essential role in phototransduction by presenting the Gqalpha-subunit to rhodopsin GPCRs for efficient activation, and preventing spontaneous GDP-GTP exchange on the Gqalpha-subunit.
   
 
 0.717
norpA
1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase; The production of the second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) is mediated by activated phosphatidylinositol-specific phospholipase C enzymes (By similarity). Essential component of the phototransduction pathway. Essential downstream component of a hh-signaling pathway which regulates the Duox-dependent gut immune response to bacterial uracil; required for the activation of Cad99C and consequently Cad99C-dependent endosome formation, which is essential for the Duox-dependent product [...]
   
  
 0.678
Sws1
SWIM domain containing Srs2 interacting protein 1 (Sws1) encodes a protein that is paralog-interacting of the product of spn-A. It is involved in homologous recombination in the repair of double-strand breaks, likely through the product of spn-A regulation.
      
 0.662
Arr1
Phosrestin-2; Regulates photoreceptor cell deactivation. Arr1 and Arr2 proteins are mediators of rhodopsin inactivation and are essential for the termination of the phototransduction cascade.
   
 
 0.648
Pph13
PvuII-PstI homology 13 (Pph13) encodes a paired-class homeodomain protein. It is critical for rhabdomeric photoreceptor differentiation, phototransduction and rhabdomere morphogenesis.
   
  
 0.613
Galphaq
G protein alpha q subunit; Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems. Could be the transducin analog, an amplifier and one of the transducers of a visual impulse that performs the coupling between opsin and cGMP-phosphodiesterase. Could mediate a subset of olfactory and gustatory responses.
    
 
 0.613
Rh4
Opsin Rh4; Visual pigments are the light-absorbing molecules that mediate vision. They consist of an apoprotein, opsin, covalently linked to cis-retinal.
  
  
0.600
rha
Rha (rha) encodes a protein that is postmeiotically present in spermatid nuclei and might be involved in the chromatin substitution process removing histones from the chromatin during sperm development.
