"AT1G30590" - RNA polymerase I specific transcription initiation factor RRN3 protein in Arabidopsis thaliana
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

AT1G30590RNA polymerase I specific transcription initiation factor RRN3 protein (604 aa)    
Predicted Functional Partners:
NRPA2
Nuclear RNA polymerase A2; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Second largest core component of RNA polymerase I which synthesizes ribosomal RNA precursors. Proposed to contribute to the polymerase catalytic activity and forms the polymerase active center together with the largest subunit. Pol I is composed of mobile elements and NRPA2 is part of the core element with the central large cleft and probably a clamp element that moves to open and close the cleft (1178 aa)
     
 
  0.905
NRPA1
Nuclear RNA polymerase A1; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Largest and catalytic core component of RNA polymerase I which synthesizes ribosomal RNA precursors. Forms the polymerase active center together with the second largest subunit. A single stranded DNA template strand of the promoter is positioned within the central active site cleft of Pol I. A bridging helix emanates from NRPA1 and crosses the cleft near the catalytic site and is thought to promote translocation of Pol I by actin [...] (1670 aa)

NRPB2
DNA-directed RNA polymerase II subunit RPB2; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Second largest component of RNA polymerase II which synthesizes mRNA precursors and many functional non-coding RNAs. Proposed to contribute to the polymerase catalytic activity and forms the polymerase active center together with the largest subunit. Pol II is the central component of the basal RNA polymerase II transcription machinery. It is composed of mobile elements that move relative to each other. NRPB2 is [...] (1188 aa)

  0.630
NRPC2
Nuclear RNA polymerase C2; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Second largest core component of RNA polymerase III which synthesizes small RNAs, such as 5S rRNA and tRNAs. Proposed to contribute to the polymerase catalytic activity and forms the polymerase active center together with the largest subunit. Pol III is composed of mobile elements and NRPC2 is part of the core element with the central large cleft and probably a clamp element that moves to open and close the cleft (1161 aa)

HMGS
HYDROXYMETHYLGLUTARYL-COA SYNTHASE; This enzyme condenses acetyl-CoA with acetoacetyl-CoA to form HMG-CoA, which is the substrate for HMG-CoA reductase. Devoided of acetoacetyl-CoA thiolase (AACT) activity. Required for the development of both tapetosomes and elaioplasts in tapetal cells and for pollen viability during pollen tube elongation (461 aa)
       
      0.557
LST8-1
Lethal with Sec Thirteen 8-1 (305 aa)
     
 
    0.556
NRPD2A
Nuclear RNA polymerase D2A; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Second largest component of RNA polymerases IV and V which mediate short-interfering RNAs (siRNA) accumulation and subsequent RNA-directed DNA methylation-dependent (RdDM) transcriptional gene silencing (TGS) of endogenous repeated sequences, including transposable elements. Proposed to contribute to the polymerase catalytic activity and forms the polymerase active center together with the largest subunit. Also required for full [...] (1172 aa)

NRPD1B
Nuclear RNA polymerase D1B; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Largest and catalytic component of RNA polymerase V involved in RNA-directed DNA methylation-dependent (RdDM) silencing of endogenous repeated sequences, including transposable elements. Also required for full erasure of methylation when the RNA trigger is withdrawn. Seems also involved in the synthesis of short-interfering RNAs (siRNA). Essential component of a self- reinforcing loop coupling de novo DNA methylation to siRNA pr [...] (1976 aa)

RAPTOR1
Regulatory associated protein of mTOR; Probable component of the plant TOR kinase pathway that recruits substrates for TOR. Modulates plant cell growth and regulates the activity of ATPK1 kinase in response to osmotic stress (1344 aa)
