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

r2d2R2d2, isoform A; R2d2 (r2d2) encodes a double-stranded RNA-binding protein. It interacts with the product of Dcr-2 to form the core of RISC loading complex, which recruits duplex siRNA to the RISC. (311 aa)    
Predicted Functional Partners:
Dcr-2
Dicer-2, isoform A; Dicer-2 (Dcr-2) encodes a member of the RNase III family of double-stranded RNA-specific endonucleases. It acts in the RNAi pathway by cutting long dsRNA into siRNAs. It helps defend flies against viral infection, particularly RNA viruses. It also processes long, partially double-stranded endogenous transcripts (hairpin RNAs) into endo-siRNAs.

drosha
Ribonuclease; Drosha (drosha) encodes a protein that contributes to miRNA processing. It is involved in salivary gland histolysis and oocyte development.
    
 0.995
AGO1
Argonaute-1, isoform A; Argonaute-1 (AGO1) encodes an Argonaute/Piwi family protein, which interacts with microRNAs to form miRNA-induced silencing complexes (miRISCs). miRISCs are guided to target and repress mRNAs either by transcript destabilisation, translational inhibition, or both.
    
 0.993
Dcr-1
Endoribonuclease Dcr-1; Essential for RNA interference (RNAi); double-stranded RNA (dsRNA) induces potent and specific gene silencing. RNAi is mediated by the RNA-induced silencing complex (RISC), a sequence-specific, multicomponent nuclease that destroys or silences messenger RNAs homologous to the silencing trigger. May carry out the initiation step of RNAi by cleaving dsRNA to produce 22 bp dsRNAs (siRNAs) which target the selective destruction of homologous RNAs. During embryogenesis, involved in germline fate determination; Belongs to the helicase family. Dicer subfamily.

AGO2
Protein argonaute-2; Essential for RNA interference (RNAi); double-stranded RNA induces potent and specific gene silencing. RNAi is mediated by the RNA-induced silencing complex (RISC), a sequence-specific, multicomponent nuclease that destroys or silences messenger RNAs homologous to the silencing trigger; Belongs to the argonaute family. Ago subfamily.

Taf11
TBP-associated factor 11 (Taf11) encodes a protein that forms part of the multisubunit basal transcription factor TFIID. It enhances RNA interference efficiency, organizing the assembly of the RISC loading complex.
   
 0.979
Tudor-SN
Staphylococcal nuclease domain-containing protein 1; Endonuclease which shows activity towards both DNA and RNA substrates. Has a role in translation regulation throught its association with the with the RNA- induced silencing complex (RISC). Plays a role in spermatogenesis probably by negatively regulating piwi expression in the germline. Together with piwi, might be involved in transposon repression in the germline.
   
 
 0.976
pasha
Partner of drosha (pasha) encodes a protein involved in oogenesis and miRNA processing.
   
 0.972
loqs
Loquacious, isoform B; Loquacious (loqs) encodes a double-stranded RNA binding protein with multiple splicing isoforms. loqs-PB and loqs-PA associate with the product of Dcr-1 to facilitate processing of precursor miRNA into mature miRNA, whereas loqs-PD interacts with the product of Dcr-2 to enhance processing of dsRNA into siRNA.
   
0.921
vig
Vasa intronic gene (vig) encodes a protein involved in RNA interference and heterochromatin organization.
