STRINGSTRING
SPX3 protein (Arabidopsis thaliana) - STRING interaction network
"SPX3" - SPX domain-containing protein 3 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

SPX3SPX domain-containing protein 3; Plays a positive role in plant adaptation to phosphate starvation and exerts negative feedback regulation of SPX1 (245 aa)    
Predicted Functional Partners:
MGD2
Monogalactosyldiacylglycerol synthase 2, chloroplastic; Involved in the synthesis of the major structural component of photosynthetic membranes and in the chloroplast envelope biogenesis. Can use both prokaryotic (18-1/16-0) or eukaryotic (18-2/18-2) 1,2-diacylglycerol species, but operates with some preference for the eukaryotic one; Belongs to the glycosyltransferase 28 family (468 aa)
     
   
  0.819
MGDC
Monogalactosyldiacylglycerol synthase 3, chloroplastic; Involved in the synthesis of the major structural component of photosynthetic membranes and in the chloroplast envelope biogenesis. Can use both prokaryotic (18-1/16-0) or eukaryotic (18-2/18-2) 1,2-diacylglycerol species, but operates with some preference for the eukaryotic one (465 aa)
     
   
  0.813
SQD2
Sulfoquinovosyl transferase SQD2; Catalyzes the transfer of the sulfoquinovose moiety from UDP-sulfoquinovose to diacylglycerol during sulfolipid biosynthesis. Sulfolipid contributes to maintaining a negatively charged lipid-water interface, a requirement for proper function of photosynthetic membranes. Sulfolipid may also function as a substitute of anionic phospholipids under phosphate-limited growth conditions (510 aa)
   
   
  0.811
PHO1
Phosphate transporter PHO1; Inositol polyphosphate sensor that associates with transcription factors to regulate inorganic phosphate (Pi) starvation responses. Probably acts by binding inositol polyphosphate via its SPX domain. Acts as a Pi exporter, mediating efflux of Pi out of cells. Transfers Pi from the epidermal and cortical cells to the root xylem vessels. Involved in the transfer of Pi from roots to shoots. Involved in abscisic acid (ABA) induction of stomatal closure and ABA repression of stomatal opening; Belongs to the SYG1 (TC 2.A.94) family (782 aa)
           
  0.794
AT1G14040
Phosphate transporter PHO1 homolog 3; May transport inorganic phosphate (Pi); Belongs to the SYG1 (TC 2.A.94) family (813 aa)
           
  0.791
RNS1
Member of the ribonuclease T2 family, responds to inorganic phosphate starvation, and inhibits production of anthocyanin. Also involved in wound-induced signaling independent of jasmonic acid (230 aa)
     
   
  0.762
PHF1
Phosphate transporter traffic facilitator1; Encodes a plant specific protein structurally related to the SEC12 proteins of the early secretory pathway. Mutation of PHF1 impairs Pi transport. Expression was detected in all tissues, and was induced by Pi starvation. Localized in endoplasmic reticulum (ER), and mutation of PHF1 resulted in ER retention and reduced accumulation of the plasma membrane PHT1;1 transporter (398 aa)
     
   
  0.738
PHT1;4
Encodes Pht1;4, a member of the Pht1 family of phosphate transporters which include- Pht1;1/At5g43350, Pht1;2/At5g43370, Pht1;3/At5g43360, Pht1;4/At2g38940, Pht1;5/At2g32830, Pht1;6/At5g43340, Pht1;7/At3g54700, Pht1;8/At1g20860, Pht1;9/At1g76430 (Plant Journal 2002, 31-341) (534 aa)
     
 
  0.738
PHO1;H1
Phosphate transporter PHO1 homolog 1; Encodes PHO1;H1, a member of the PHO1 family. Involved in inorganic phosphate (Pi) transport and homeostasis. Complements pho1 mutation (784 aa)
     
   
  0.737
SQD1
UDP-sulfoquinovose synthase, chloroplastic; Involved in the biosynthesis of sulfolipids found in thylakoid membranes. Converts UDP-glucose and sulfite to the sulfolipid head group precursor UDP-sulfoquinovose; Belongs to the NAD(P)-dependent epimerase/dehydratase family (477 aa)
