STRINGSTRING
STRING protein interaction network
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

PSAE-2Photosystem I reaction center subunit IV B, chloroplastic; Stabilizes the interaction between PsaC and the PSI core, assists the docking of the ferredoxin to PSI and interacts with ferredoxin-NADP oxidoreductase (145 aa)    
Predicted Functional Partners:
PSAD-2
Photosystem I reaction center subunit II-2, chloroplastic; PSAD can form complexes with ferredoxin and ferredoxin- oxidoreductase in photosystem I (PS I) reaction center. PSAD may encode the ferredoxin-docking protein (By similarity)
  
 0.998
PSAF
Photosystem I reaction center subunit III, chloroplastic; Participates in efficiency of electron transfer from plastocyanin to P700 (or cytochrome c553 in algae and cyanobacteria). This plastocyanin-docking protein contributes to the specific association of plastocyanin to PSI
  
 0.998
PSAD-1
Photosystem I reaction center subunit II-1, chloroplastic; PsaD can form complexes with ferredoxin and ferredoxin- oxidoreductase in photosystem I (PS I) reaction center. PSAD may encode the ferredoxin-docking protein
  
 0.997
PSAL
Encodes subunit L of photosystem I reaction center; Belongs to the PsaL family
  
 0.996
PSAK
Encodes subunit K of photosystem I reaction center
   
 0.992
PSAH2
Photosystem I reaction center subunit VI-2, chloroplastic; Possible role could be the docking of the LHC I antenna complex to the core complex
   
 0.988
PSAG
Photosystem I reaction center subunit V, chloroplastic; Encodes subunit G of photosystem I, an 11-kDa membrane protein that plays an important role in electron transport between plastocyanin and PSI and is involved in the stability of the PSI complex. PSI-G subunit is bound to PSI-B and is in contact with Lhca1. The protein inserts into thylakoids by a direct or "spontaneous" pathway that does not involve the activities of any known chloroplast protein-targeting machinery. PSI-G appears to be directly or indirectly involved in the interaction between Photosystem I and plastocyanin
   
 0.988
LHCA1
Chlorophyll a-b binding protein 6, chloroplastic; The light-harvesting complex (LHC) functions as a light receptor, it captures and delivers excitation energy to photosystems with which it is closely associated
   
 0.988
PSAO
Photosystem I subunit O; Involved in the balancing of excitation energy between the two photosystems I (PSI) and II (PSII); Belongs to the PSAO family
   
 0.986
PSAH-1
Photosystem I reaction center subunit VI-1, chloroplastic; Possible role could be the docking of the LHC I antenna complex to the core complex
   
 0.986
