STRINGSTRING
SOM protein (Arabidopsis thaliana) - STRING interaction network
SOMNUS 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

SOMSOMNUS; Probable transcription repressor that functions as negative regulator of phytochrome-mediated promotion of seed germination. Inhibits seed germination by regulating the expression of gibberellic acid (GA) and abscisic acid (ABA) metabolic genes. Does not regulate the expression of the DELLA genes RGA and RGA1. Activated by PIL5, a phytochrome-interacting basic helix-loop-helix transcription factor (393 aa)    
Predicted Functional Partners:
PIL5
Transcription factor PIF1; Transcription activator. Regulates negatively chlorophyll biosynthesis and seed germination in the dark, and lightinduced degradation of PIF1 relieves this negative regulation to promote photomorphogenesis. Binds to the G-box motif (5’- CACGTG-3’) found in many light-regulated promoters. Promotes the expression of SOM, and thus modulates responses to abscisic acid (ABA) and gibberellic acid (GA) (478 aa)
           
  0.806
XERICO
RING/U-box domain-containing protein; Function on abscisic acid homeostasis at post- translational level, probably through ubiquitin/proteasome- dependent substrate-specific degradation (162 aa)
       
 
  0.555
UBC19
Ubiquitin-conjugating enzyme19; Accepts the ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. Part of the anaphase- promoting complex (APC). May have a key function during cell cycle and be involved in cyclin B1 degradation (181 aa)
     
      0.501
UBC20
Ubiquitin-conjugating enzyme 20; Accepts the ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins (180 aa)
     
      0.501
AT4G02620
V-type proton ATPase subunit F; Subunit of the peripheral V1 complex of vacuolar ATPase essential for assembly or catalytic function. V-ATPase is responsible for acidifying a variety of intracellular compartments in eukaryotic cells (By similarity) (128 aa)
       
      0.493
EM1
Em-like protein GEA1; It is thought to provide protection for the cytoplasm during the desiccation stage of embryo development (152 aa)
           
  0.493
SAE2
SUMO-activating enzyme 2; The dimeric enzyme acts as a E1 ligase for SUMO1 and SUMO2. It mediates ATP-dependent activation of SUMO proteins and formation of a thioester with a conserved cysteine residue on SAE2 (700 aa)
       
      0.493
AT1G77550
Tubulin-tyrosine ligase (855 aa)
       
      0.493
SRX
Sulfiredoxin; Contributes to oxidative stress resistance by reducing cysteine-sulfinic acid formed under exposure to oxidants in a peroxiredoxin. May catalyze the reduction in a multi-step process by acting both as a specific phosphotransferase and a thioltransferase. Required to switch on the antioxidant pathway to regenerate the oxidative damage. In mitochondrion, catalyzes the retroreduction of the inactive sulfinic form of atypical Prx IIF using thioredoxin as reducing agent (198 aa)
       
      0.493
AT1G27530
Ubiquitin-fold modifier-conjugating enzyme 1; E2-like enzyme which forms an intermediate with UFM1 via a thioester linkage (174 aa)
       
      0.493
