STRINGSTRING
NAS3 protein (Arabidopsis thaliana) - STRING interaction network
"NAS3" - Nicotianamine synthase 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

NAS3Nicotianamine synthase 3; Synthesizes nicotianamine, a polyamine which serves as a sensor for the physiological iron status within the plant, and/or might be involved in the transport of iron; Belongs to the nicotianamine synthase (NAS)-like family (320 aa)    
Predicted Functional Partners:
MT2A
Metallothionein-like protein 2A; Metallothioneins have a high content of cysteine residues that bind various heavy metals (Probable). Functions as metal chelator of copper (Cu) and zinc (Zn). Plays a role in Cu homeostasis, specifically in the remobilization of Cu from senescing leaves. The mobilization of Cu from internal sources is important for seed development (81 aa)
           
  0.776
IRT2
Iron regulated transporter 2; High-affinity iron transporter that mediates under iron- deficiency the iron uptake from the rhizosphere across the plasma membrane in the root epidermal layer. Could also be capable of transporting zinc ions (350 aa)
           
  0.749
IRT1
Iron-regulated transporter 1; High-affinity iron transporter that plays a key role in the uptake of iron from the rhizosphere across the plasma membrane in the root epidermal layer. Acts as the principal regulator of iron homeostasis in planta. Also mediates the heavy metals uptake under iron-deficiency by its ability to transport cobalt, cadmium, manganese and/or zinc ions (347 aa)
           
  0.741
FRD3
MATE efflux family protein; Encodes a member of the MATE (multidrug and toxin efflux family), expressed in roots but not shoots. Mutants accumulate excess iron, manganese and zinc, and express root Fe(III) chelatase activity even under iron sufficiency conditions. FRD3 is likely to function in root xylem loading of an iron chelator or other factor necessary for efficient iron uptake out of the xylem or apoplastic space and into leaf cells; Belongs to the multi antimicrobial extrusion (MATE) (TC 2.A.66.1) family (526 aa)
           
  0.738
FER4
Ferritin-4, chloroplastic; Encodes FERRITIN 4, AtFER4. Ferritins are a class of 24-mer multi-meric proteins found in all kingdoms of life. Function as the main iron store in mammals. Evidence suggests that Arabidopsis ferritins are essential to protect cells against oxidative damage, but they do not constitute the major iron pool. Localize to mitochondria. Knock out mutants are not sensitive to abiotic stress (259 aa)
     
   
  0.734
YSL1
Metal-nicotianamine transporter YSL1; Involved in iron loading of the seeds. Acts probably as a transporter of iron- and metal-nicotianamine chelates; Belongs to the YSL (TC 2.A.67.2) family (673 aa)
     
   
  0.719
FER1
Ferritin-1, chloroplastic; Encodes a ferretin protein that is targeted to the chloroplast. Member of a Ferritin gene family. Gene expression is induced in response to iron overload and by nitric oxide. Expression of the gene is downregulated in the presence of paraquat, an inducer of photoxidative stress (255 aa)
     
   
  0.698
YSL2
Metal-nicotianamine transporter YSL2; Closest Arabidopsis homolog of Zea maize metal-phytosiderophore/metal-nicotianamine transporter ZmYS1 (664 aa)
           
  0.646
AGO10
Stabilizer of iron transporter SufD / Polynucleotidyl transferase; Involved in RNA-mediated post-transcriptional gene silencing (PTGS). Main component of the RNA-induced silencing complex (RISC) that binds to a short guide RNA such as a microRNA (miRNA) or small interfering RNA (siRNA). RISC uses the mature miRNA or siRNA as a guide for slicer-directed cleavage of homologous mRNAs to repress gene expression. Required for reliable formation of primary and axillary shoot apical meristems. Specifies leaf adaxial identity by repressing the miR165 and miR166 microRNAs in the embryonic shoot [...] (988 aa)
           
  0.633
FRO2
Ferric reduction oxidase 2; Encodes the low-iron-inducible ferric chelate reductase responsible for reduction of iron at the root surface. It is likely to be the major Fe(III) chelate reductase in Arabidopsis iron metabolism. Coordinately regulated with IRT1, the major transporter responsible for high-affinity iron uptake from the soil, at both transcriptional and posttranscriptional levels. Steady state mRNA levels are regulated by several metals. Its transcription is regulated by FIT1 (725 aa)
