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

trplTransient-receptor-potential-like protein; A light-sensitive calcium channel that is required for inositide-mediated Ca(2+) entry in the retina during phospholipase C (PLC)-mediated phototransduction. Required for vision in the dark and in dim light. Binds calmodulin. Trp and trpl act together in the light response, although it is unclear whether as heteromultimers or distinct units. Also forms a functional cation channel with Trpgamma. Activated by fatty acids, metabolic stress, inositols and GTP-binding proteins. (1124 aa)    
Predicted Functional Partners:
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.

ninaE
Opsin Rh1; Neither inactivation nor afterpotential E (ninaE) encodes a protein that plays a major role in light detection and vision. It is the rhodopsin expressed in the largest class of photoreceptors in the adult retina. The stimulation by light of the product of ninaE induces G-protein signaling activation, the opening of the channels encoded by trp and trpl and photoreceptor cell membrane depolarization.

trp
Transient receptor potential protein; A light-sensitive calcium channel that is required for inositide-mediated Ca(2+) entry in the retina during phospholipase C (PLC)-mediated phototransduction. Ca(2+) influx may then feed back and inhibit PLC, thereby facilitating phosphatidylinositol 4,5 bisphosphate (PIP2) recycling. Trp and trpl act together in the light response, though it is unclear whether as heteromultimers or as distinct units, and are activated by fatty acids and metabolic stress. Also required for olfactory adaptation and may be involved in olfactory system development. Bel [...]

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 [...]
   
 0.976
ninaC
Neither inactivation nor afterpotential protein C; Required for photoreceptor cell function. The ninaC proteins combines putative serine/threonine-protein kinase and myosin activities. Essential for the expression and stability of the rtp protein in the photoreceptors. The rtp/ninaC complex is required for stability of inad and inac and the normal termination of phototransduction in the retina.
   
 
 0.974
inaC
Protein kinase C, eye isozyme; This is a calcium-activated, phospholipid-dependent, serine- and threonine-specific enzyme. This isozyme is a negative regulator of the visual transduction cascade and has been shown to be required for photoreceptor cell inactivation and light adaptation. Negative regulation is dependent on interaction with scaffolding protein inaD. Acts in 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 [...]

Arr2
Phosrestin-1; Arrestin 2 (Arr2) encodes a protein involved in rhodopsin inactivation that contributes to photoreceptor maintenance and smell and sound perception.
   
  
 0.966
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.
     
 0.952
Cam
Calmodulin; Calmodulin mediates the control of a large number of enzymes, ion channels and other proteins by Ca(2+) (By similarity). Among the enzymes to be stimulated by the calmodulin-Ca(2+) complex are a number of protein kinases and phosphatases (By similarity). In photoreceptor cells, light-induced Ca(2+) influx activates calmodulin, which in turn is likely to promote Crag activity in trafficking of newly synthesized ninaE (Rh1) from the trans-Golgi network to rhabdomere membranes. Together with Akap200, regulates PKA activity and ethanol-induced sensitivity and tolerance.
    
 
 0.948
TrpA1
Transient receptor potential cation channel A1 (TrpA1) encodes a cation channel activated by warming and by reactive chemicals. Its roles include the control of thermotaxis at innocuous temperatures, as well as thermal and chemical nociception in response to noxious heat and chemical exposure.
