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

nrde-1Uncharacterized protein. (793 aa)    
Predicted Functional Partners:
nrde-4
Uncharacterized protein.
   
  
 0.967
nrde-2
Nuclear exosome regulator NRDE2; Protein of the nuclear speckles that regulates RNA exosomal degradation (By similarity). Involved in short interfering RNAs- mediated silencing in nuclei. Functions with nrde-3 in the nuclear RNA-mediated gene silencing (RNAi) pathway to regulate gene expression via inhibition of RNA polymerase II during the elongation phase of transcription. Required for exogenous RNAi-induced H3K27 methylation. Belongs to the NRDE2 family.
   
  
 0.923
hrde-1
Uncharacterized protein C16C10.3.
   
  
 0.914
nrde-3
Nuclear RNAi defective-3 protein; Transports small interfering RNAs (siRNAs) from the cytoplasm to the nucleus. Required for RNA interference (RNAi) in nuclei. Required for exogenous RNAi-induced H3K27 methylation.
   
  
 0.894
set-32
SET domain-containing protein.
   
  
 0.825
hpl-2
Chromo domain-containing protein.
   
  
 0.804
set-25
Histone-lysine N-methyltransferase set-25; Histone methyltransferase that specifically trimethylates 'Lys-9' of histone H3 using mono- and dimethylated H3 'Lys-9' as substrate. Acts redundantly with the methyltransferase met-2 to position chromosome arms at the nuclear lamina. Required for small-RNA-induced H3K9 methylation. Together with met-2, protects and stabilizes repeat-rich genomic regions by suppressing transcription- induced replication stress through methylation of H3K9.
   
  
 0.760
prg-1
Piwi-like protein; Belongs to the argonaute family.
   
  
 0.706
morc-1
Protein morc-1; Involved in gene silencing. Plays a role in germline RNA interference (RNAi), and in particular, the silencing of endogenous small interfering RNA (endo-siRNA) target genes. May play a role in heterochromatin localization and condensation, and the siRNAi-directed trimethylation of 'Lys-9' of histone H3 in hermaphrodite X chromosomes. Promotes transgenerational epigenetic inheritance and germline immortality.
   
  
 0.673
wago-1
Argonaute protein wago-1; Argonaute protein which is involved in the endogenous small interfering RNA (endo-siRNA) pathway. Interacts with secondary 22G- RNAs, which are RNA-dependent RNA polymerase-derived endo-siRNAs, typically 22 nucleotides in length with a 5'guanosine residue. In the germline, functions in a genome surveillance system to silence transposons and aberrant transcripts.
