STRINGSTRING
PSAF protein (Arabidopsis thaliana) - STRING interaction network
"PSAF" - Photosystem I subunit F 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

PSAFPhotosystem I subunit F; 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 (221 aa)    
Predicted Functional Partners:
PSAL
Photosystem I subunit l (219 aa)
 
  0.999
PSAD-1
Photosystem I subunit D-1; PsaD can form complexes with ferredoxin and ferredoxin- oxidoreductase in photosystem I (PS I) reaction center. PSAD may encode the ferredoxin-docking protein (208 aa)
   
  0.999
PSAD-2
Photosystem I subunit D-2; 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) (204 aa)
   
  0.999
PSAE-1
PSA E1 KNOCKOUT; Stabilizes the interaction between PsaC and the PSI core, assists the docking of the ferredoxin to PSI and interacts with ferredoxin-NADP oxidoreductase (143 aa)
   
  0.998
PSAA
Photosystem I, PsaA/PsaB protein.[Source-TAIR;Acc-ATCG00350]; PsaA and PsaB bind P700, the primary electron donor of photosystem I (PSI), as well as the electron acceptors A0, A1 and FX. PSI is a plastocyanin-ferredoxin oxidoreductase, converting photonic excitation into a charge separation, which transfers an electron from the donor P700 chlorophyll pair to the spectroscopically characterized acceptors A0, A1, FX, FA and FB in turn. Oxidized P700 is reduced on the lumenal side of the thylakoid membrane by plastocyanin (750 aa)
   
 
  0.998
LHCA1
Photosystem I light harvesting complex gene 1; The light-harvesting complex (LHC) functions as a light receptor, it captures and delivers excitation energy to photosystems with which it is closely associated (241 aa)
     
  0.998
PSAE-2
Photosystem I subunit E-2; 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)
   
  0.997
LHCA3
Photosystem I light harvesting complex gene 3; The light-harvesting complex (LHC) functions as a light receptor, it captures and delivers excitation energy to photosystems with which it is closely associated, here photosystem I (273 aa)
     
  0.997
PSAB
Encodes the D1 subunit of photosystem I reaction center; PsaA and PsaB bind P700, the primary electron donor of photosystem I (PSI), as well as the electron acceptors A0, A1 and FX. PSI is a plastocyanin-ferredoxin oxidoreductase, converting photonic excitation into a charge separation, which transfers an electron from the donor P700 chlorophyll pair to the spectroscopically characterized acceptors A0, A1, FX, FA and FB in turn. Oxidized P700 is reduced on the lumenal side of the thylakoid membrane by plastocyanin (734 aa)
   
 
  0.997
PSAN
Photosystem I reaction center subunit N; May function in mediating the binding of the antenna complexes to the PSI reaction center and core antenna. Plays an important role in docking plastocyanin to the PSI complex. Does not bind pigments (181 aa)
