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

ninaAPeptidyl-prolyl cis-trans isomerase, rhodopsin-specific isozyme; PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. Acts on the folding of rhodopsin RH1 and RH2 (but not RH3) and is required for visual transduction. Belongs to the cyclophilin-type PPIase family. (237 aa)    
Predicted Functional Partners:
Cpn
Calphotin (Cpn) encodes a glutamic acid-rich protein with a strong negative charge and a highly hydrophobic amino acid composition. It functions as an immobile Ca[2+] buffer along the base of the photoreceptor's microvilli. It protects the photoreceptor cells from Ca[2+] overload and light induced degeneration.

CG1671
LD47550p; U3 snoRNA binding. It is involved in the biological process described with: endonucleolytic cleavage to generate mature 5'-end of SSU-rRNA from (SSU-rRNA, 5.8S rRNA, LSU-rRNA); endonucleolytic cleavage in 5'-ETS of tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA).

Fib
rRNA 2'-O-methyltransferase fibrillarin; S-adenosyl-L-methionine-dependent methyltransferase that has the ability to methylate both RNAs and proteins. Involved in pre-rRNA processing. Utilizes the methyl donor S-adenosyl-L-methionine to catalyze the site-specific 2'-hydroxyl methylation of ribose moieties in pre-ribosomal RNA. Site specificity is provided by a guide RNA that base pairs with the substrate. Methylation occurs at a characteristic distance from the sequence involved in base pairing with the guide RNA. Also acts as a protein methyltransferase by mediating methylation of 'Gl [...]

CG10909
IP10714p; rRNA methyltransferase activity; histone-glutamine methyltransferase activity; RNA binding. It is involved in the biological process described with: rRNA methylation; box C/D snoRNA 3'-end processing; histone glutamine methylation.

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.

mt:ND4
NADH-ubiquinone oxidoreductase chain 4; Core subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) that is believed to belong to the minimal assembly required for catalysis. Complex I functions in the transfer of electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone (By similarity).
   
 
 0.744
ninaG
Neither inactivation nor afterpotential protein G; Oxidoreductase involved in biosynthesis of 3-hydroxyretinal, a chromophore for rhodopsin Rh1. Not responsible for the initial hydroxylation of the retinal ring but rather acts in a subsequent step in chromophore production. May catalyze the conversion of (3R)-3- hydroxyretinol to the 3S enantiomer.

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.

l(1)G0020
RNA cytidine acetyltransferase; RNA cytidine acetyltransferase with specificity toward both 18S rRNA and tRNAs. Catalyzes the formation of N(4)-acetylcytidine (ac4C) in 18S rRNA. Required for early nucleolar cleavages of precursor rRNA at sites A0, A1 and A2 during 18S rRNA synthesis. Catalyzes the formation of ac4C in serine and leucine tRNAs. Requires a tRNA-binding adapter protein for full tRNA acetyltransferase activity but not for 18S rRNA acetylation (Probable). Polycomb group (PcG) protein. PcG proteins act by forming multiprotein complexes, which are required to maintain the tr [...]
