STRINGSTRING
SHH1 protein (Arabidopsis thaliana) - STRING interaction network
"SHH1" - Uncharacterized 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

SHH1Uncharacterized protein; Involved in RNA-directed DNA methylation (RdDM). Required for the silencing of some endogenous RdDM targets and accumulation of 24-nt siRNAs, but not for the production of Pol V- dependent transcripts. Functions in transcriptional silencing through both DNA methylation-dependent and -independent pathways. Required for both maintenance and de-novo DNA methylation. Plays a role in the recruitment of Pol IV to genomic regions associated with K9 methylated histone H3 that are targets for RdDM (258 aa)    
Predicted Functional Partners:
CHR38
Chromatin remodeling 38; Probable chromatin remodeling factor. Required for the initial establishment of DNA methylation and for accumulation of 24-nt siRNAs. May act on RNA templates by remodeling ribonucleoprotein structures and thereby influencing the availability of the RNA to polymerases (1256 aa)
       
 
  0.950
RDR2
RNA-dependent RNA polymerase 2; RNA-dependent direct polymerase involved in the production of small interfering RNAs (siRNAs). Required for the biogenesis of endogenous siRNAs of 24 nucleotide which derive from heterochromatin and DNA repeats such as transposons or endogenous gene tandem repeats, such as repeats present in FWA gene. Involved in transcriptional gene silencing (TGS). Component of the RNA- directed DNA methylation (RdDM) silencing pathway that utilizes siRNAs to guide DNA methyltransferases to asymmetric cytosines. Involved in control of flowering time through RdDM of FWA [...] (1133 aa)

NRPD1A
Nuclear RNA polymerase D1A; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates (By similarity). Largest and catalytic component of RNA polymerase IV which mediates 24-nt short-interfering RNAs (siRNA) accumulation. Implicated in siRNA-directed heterochromatin formation through the action of DCL3 and AGO4, and subsequent DNA methylation-dependent silencing of targeted sequences. Essential component of a self-reinforcing loop coupling de novo DNA methylation to siRNA production. Required for intercellular but [...] (1453 aa)
     
 
  0.902
RDM1
RNA-DIRECTED DNA METHYLATION 1; Regulator of RNA-directed DNA methylation (RdDM). Binds to single-stranded methyl DNA. Involved in the assembly of RNA polymerase V (Pol V) transcription initiation or elongation complexes at the chromatin, as a component of the DDR complex (163 aa)
           
  0.844
POL
Poltergeist; Involved in the regulation of pedicel length and of CLAVATA pathways controlling stem cell identity at shoot and flower meristems (856 aa)

CHR42
Chromatin remodeling 42; Probable chromatin remodeling factor (1261 aa)
       
 
  0.825
NRPB3
DNA-directed RNA polymerase II subunit RPB3-A; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Component of RNA polymerase II which synthesizes mRNA precursors and many functional non-coding RNAs. 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. NRPB3 is part of the core element with the central large cleft and the clamp element that moves to open and close the cleft. Component of RNA polymerases I [...] (319 aa)

NRPE3B
DNA-directed RNA polymerase II subunit RPB3-B; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. 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 (319 aa)

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)

DMS3
DEFECTIVE IN MERISTEM SILENCING 3; Component of the RNA-directed DNA methylation (RdDM) machinery, probably by facilitating an RNAi-mediated epigenetic modification involving secondary siRNAs and spreading of DNA methylation, thus leading to gene silencing. Involved in the assembly of RNA polymerase V (Pol V) transcription initiation or elongation complexes at the chromatin, as a component of the DDR complex. Required for de novo DNA methylation (420 aa)
