FNR2 protein (Arabidopsis thaliana) - STRING interaction network
"FNR2" - Ferredoxin--NADP reductase, leaf isozyme 2, chloroplastic 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
Your Input:
Gene Fusion
FNR2Ferredoxin--NADP reductase, leaf isozyme 2, chloroplastic; Encodes a leaf-type ferredoxin-NADP(H) oxidoreductase. It is present in both chloroplast stroma and thylakoid membranes but is more abundant in the stroma (369 aa)    
Predicted Functional Partners:
ATP synthase gamma chain 1, chloroplastic; Produces ATP from ADP in the presence of a proton gradient across the membrane. The gamma chain is believed to be important in regulating ATPase activity and the flow of protons through the CF(0) complex (373 aa)
NAD(P)-binding Rossmann-fold superfamily protein; Involved in protein precursor import into chloroplasts. Part of the redox regulon consisting of TIC32, TIC 55 and TIC62. Acts as a membrane anchor of LFNR1 and LFNR2. Has a NADPH-dependent dehydrogenase activity, but only after preincubation with lipids (By similarity) (641 aa)
Ferredoxin--NADP reductase, leaf isozyme 1, chloroplastic; Encodes a leaf-type ferredoxin-NADP(H) oxidoreductase. It is present in both chloroplast stroma and thylakoid membranes but is more abundant in the thylakoid. The affinity of this enzyme for ferredoxin is slightly, but significantly, higher than AtLFNR2, an isoform of the same enzyme. AtLFNR1 forms a heterodimer with AtFNR2 and is also a prerequisite to attach AtFNR2 to the thylakoid membrane (360 aa)
Encoding PSII-S (CP22), a ubiquitous pigment-binding protein associated with photosystem II (PSII) of higher plants. Involved in nonphotochemical quenching rather than in photosynthesis. Mutant has a normal violaxanthin cycle but has a limited capacity of quenching singlet excited chlorophylls and is tolerant to lipid peroxidation; Belongs to the ELIP/psbS family (265 aa)
2Fe-2S ferredoxin-like superfamily protein; Ferredoxins are iron-sulfur proteins that transfer electrons in a wide variety of metabolic reactions; Belongs to the 2Fe2S plant-type ferredoxin family (148 aa)
Rhodanese-like domain-containing protein 4, chloroplastic; Hydroxyproline-rich glycoprotein family protein, contains a rhodanese homology domain. Required for anchoring the FNR flavoenzyme to the thylakoid membranes and sustaining high efficiency photosynthetic linear electron flow (466 aa)
Sedoheptulose-1,7-bisphosphatase, chloroplastic; Encodes the chloroplast enzyme sedoheptulose-1,7-bisphosphatase (SBPase), involved in the carbon reduction of the Calvin cycle. Increase in SBPase activity in transgenic lines accumulate up to 50% more sucrose and starch than wild-type; Belongs to the FBPase class 1 family (393 aa)
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)
Cytochrome b6-f complex iron-sulfur subunit, chloroplastic; Essential protein for photoautotrophism. Confers resistance to photo-oxidative damages by contributing to the thermal dissipation of light energy and to lumenal acidification (increase of pH gradient). Component of the cytochrome b6-f complex, which mediates electron transfer between photosystem II (PSII) and photosystem I (PSI), cyclic electron flow around PSI, and state transitions (By similarity) (229 aa)
Chloroplast stem-loop binding protein of 41 kDa a, chloroplastic; Binds and cleaves RNA, particularly in stem-loops. Associates with pre-ribosomal particles in chloroplasts, and participates in chloroplast ribosomal RNA metabolism, probably during the final steps of 23S rRNA maturation. May enhance transcription by the plastid-encoded polymerase and translation in plastid via the stabilization of ribosome assembly intermediates. Required for chloroplast integrity. Involved in the regulation of the circadian system; Belongs to the NAD(P)-dependent epimerase/dehydratase family (406 aa)
