STRINGSTRING
NRT1.1 protein (Arabidopsis thaliana) - STRING interaction network
"NRT1.1" - Nitrate transporter 1.1 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

NRT1.1Nitrate transporter 1.1; Dual affinity nitrate transporter. Involved in proton- dependent nitrate uptake and in the regulation of the nitrate transporter NRT2.1. Acts also as a nitrate sensor that trigger a specific signaling pathway stimulating lateral root growth and seed germination. The uptake activity is not required for sensor function. Displays an auxin transport facilitation inhibited by high nitrate concentration. Required to prevent auxin accumulation in preemerged lateral root primordia and young lateral roots when external nitrate concentration is low or null. May be involv [...] (590 aa)    
Predicted Functional Partners:
NRT2:1
Nitrate transporter 2-1; Involved in nitrate transport, but does not seem to be able to mediate transport by its own. Acts as a dual component transporter with NTR3.1. Acts as a repressor of lateral root initiation under high sucrose/low nitrate conditions (530 aa)
           
  0.982
NRT2.2
Nitrate transporter 2.2; Involved in high-affinity nitrate transport (522 aa)
           
  0.957
CIPK23
CBL-interacting protein kinase 23; CIPK serine-threonine protein kinases interact with CBL proteins. Binding of a CBL protein to the regulatory NAF domain of CIPK protein leads to activation of the kinase in a calcium- dependent manner. Downstream of CBL1, CBL2, CBL3 and CBL9, regulates by phosphorylation the K(+) conductance and uptake of AKT1 in low K(+) condition, in response to calcium signaling and during the stomatal opening regulation by monitoring the turgor pressure in guard cells. In response to low nitrate concentration, phosphorylates NRT1.1, switching it from a low-affinit [...] (482 aa)

GNC
GATA transcription factor 21; Transcriptional regulator that specifically binds 5’- GATA-3’ or 5’-GAT-3’ motifs within gene promoters (398 aa)
           
  0.910
WR3
WOUND-RESPONSIVE 3; Acts as a dual component transporter with NTR2.1. Required for high-affinity nitrate transport. Acts as a repressor of lateral root initiation. May be involved in targeting NRT2 proteins to the plasma membrane (210 aa)
     
   
  0.879
NIR1
Nitrite reductase 1; Catalyzes the six-electron reduction of nitrite to ammonium (586 aa)
     
   
  0.869
NRT2.4
Nitrate transporter 2.4; Involved in high-affinity nitrate transport. Might be involved in the transfer of nitrate from stored pools to cytoplasm (527 aa)
           
  0.869
AMT1;1
Ammonium transporter 1;1; High affinity ammonium transporter probably involved in ammonium uptake from the soil, long-distance transport to the shoots and re-uptake of apoplastic ammonium that derives from photorespiration in shoots. Contributes with AMT1-3 to the overall ammonium uptake capacity in roots under nitrogen-deficiency conditions (501 aa)
     
   
  0.864
NIA1
Nitrate reductase 1; Nitrate reductase is a key enzyme involved in the first step of nitrate assimilation in plants, fungi and bacteria (917 aa)
     
   
  0.863
NRT2.5
Nitrate transporter2.5; Involved in high-affinity nitrate transport. Might be involved in the transfer of nitrate from stored pools to cytoplasm (502 aa)
