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

Dcr-2Dicer-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. (1722 aa)    
Predicted Functional Partners:
r2d2
R2d2, 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.
   
 0.999
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.

pasha
Partner of drosha (pasha) encodes a protein involved in oogenesis and miRNA processing.
   
 0.999
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.
   
 0.999
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.
   
 0.996
drosha
Ribonuclease; Drosha (drosha) encodes a protein that contributes to miRNA processing. It is involved in salivary gland histolysis and oocyte development.
   
 
0.988
Fmr1
Synaptic functional regulator FMR1; Polyribosome-associated RNA-binding protein that plays a role in neuronal development and synaptic plasticity through the regulation of protein synthesis of mRNAs. Plays a role as a negative translational regulator of specific mRNAs. Represses translation of the microtubule-associated protein futsch mRNA to regulate microtubule-dependent synaptic growth and function. May also be involved in microRNA (miRNA)-mediated translational suppression as part of the RNA-induced silencing complex (RISC). Required for stability of the central pair of microtubule [...]

Ranbp21
Ranbp21, isoform A; RNA binding; nuclear export signal receptor activity; Ran GTPase binding. It is involved in the biological process described with: regulation of protein export from nucleus; RNA export from nucleus.

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.
  
 
 0.984
piwi
Protein piwi; Acts via the piwi-interacting RNA (piRNA) metabolic process, which mediates the repression of transposable elements during meiosis by forming complexes composed of piRNAs and Piwi proteins and governs the methylation and subsequent repression of transposons. Directly binds piRNAs, a class of 24 to 30 nucleotide RNAs that are generated by a Dicer-independent mechanism and are primarily derived from transposons and other repeated sequence elements. In ovarian somatic cells, mediates silencing of transposable elements at the transcriptional level in a mael-dependent manner. [...]
