NRT2.2 protein (Arabidopsis thaliana) - STRING interaction network
"NRT2.2" - Encodes a high-affinity nitrate transporter in Arabidopsis thaliana
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 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
protein homology

NRT2.2Encodes a high-affinity nitrate transporter (522 aa)    
Predicted Functional Partners:
Ferredoxin--nitrite reductase, chloroplastic; Involved in the second step of nitrate assimilation. Its expression is induced by nitrate; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family (586 aa)
Nitrate reductase [NADH] 1; Encodes the cytosolic minor isoform of nitrate reductase (NR). Involved in the first step of nitrate assimilation, it contributes about 15% of the nitrate reductase activity in shoots. Similar to molybdopterin oxidoreductases at the N-terminus, and to FAD/NAD-binding cytochrome reductases at the C-terminus. Cofactors- FAD, heme iron (cytochrome B-557), and molybdenum-pterin (917 aa)
Nitrate reductase [NADH] 2; Identified as a mutant resistant to chlorate. Encodes nitrate reductase structural gene. Involved in nitrate assimilation. Has nitrate reductase activity. Up-regulated by the fungus P. indica. Binds transcription factor At2g35940 (917 aa)
Protein NRT1/ PTR FAMILY 6.3; 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 i [...] (590 aa)
High-affinity nitrate transporter 3.1; 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; Belongs to the NAR2 family (210 aa)
Ammonium transporter 2; High affinity ammonium transporter that may play an important role in moving ammonium between the apoplast and symplast of cells throughout the plant. Does not transport methylammonium; Belongs to the ammonia transporter channel (TC 1.A.11.2) family (475 aa)
Ammonium transporter 1 member 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)
Protein NRT1/ PTR FAMILY 7.3; Transmembrane nitrate transporter. Involved in xylem transport of nitrate from root to shoot. Induced in response to nitrate. Not involved in nitrate uptake. expressed in root pericycle cells; Belongs to the PTR2/POT transporter (TC 2.A.17) family (614 aa)
Protein NRT1/ PTR FAMILY 4.6; Low-affinity proton-dependent nitrate transporter. Involved in constitutive nitrate uptake. Not involved in histidine or dipeptides transport. Involved in (+)-abscisic acid (ABA) transport, but not in gibberellin, indole-3-acetic acid or jasmonic acid import. Mediates cellular ABA uptake. Nitrate does not compete with abscisic acid as a substrate of NPF4.6; Belongs to the PTR2/POT transporter (TC 2.A.17) family (585 aa)
Protein NRT1/ PTR FAMILY 2.13; Low-affinity proton-dependent nitrate transporter. Not involved in dipeptides transport, but has a weak glucosinolate transport activity. Involved in phloem loading and nitrate remobilization from the older leaves to other tissues; Belongs to the PTR2/POT transporter (TC 2.A.17) family (620 aa)
