STRINGSTRING
PSAO protein (Arabidopsis thaliana) - STRING interaction network
"PSAO" - Photosystem I subunit O 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

PSAOPhotosystem I subunit O; Involved in the balancing of excitation energy between the two photosystems I (PSI) and II (PSII); Belongs to the PSAO family (140 aa)    
Predicted Functional Partners:
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 (160 aa)
     
    0.999
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 (221 aa)
     
  0.999
PSAK
Encodes subunit K of photosystem I reaction center (130 aa)
     
  0.999
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 (241 aa)
     
  0.998
LHCA3
Photosystem I chlorophyll a/b-binding protein 3-1, 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, here photosystem I (273 aa)
     
    0.998
PSAL
Encodes subunit L of photosystem I reaction center; Belongs to the PsaL family (219 aa)
     
    0.998
LHCB2.1
Chlorophyll a-b binding protein 2.1, 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 (By similarity). Mediates rapid phosphorylation and migration of LHCII-PSII to photosystem I (PSI) after transition to state 2 (red) light conditions, thus leading to the formation of PSI-PSII-LHCII and PSI-LHCII supercomplex to balance the relative excitation of PSI and PSII. Involved in the production of reactive oxygen species (ROS) and stomatal closure upon abscisic acid ( [...] (265 aa)
     
  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 (208 aa)
     
    0.998
LHCB2.3
Chlorophyll a-b binding protein 2.4, 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 (By similarity). Mediates rapid phosphorylation and migration of LHCII-PSII to photosystem I (PSI) after transition to state 2 (red) light conditions, thus leading to the formation of PSI-PSII-LHCII and PSI-LHCII supercomplex to balance the relative excitation of PSI and PSII. Involved in the production of reactive oxygen species (ROS) and stomatal closure upon abscisic acid ( [...] (266 aa)

LHCB2.2
Chlorophyll a-b binding protein 2.2, 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 (By similarity). Mediates rapid phosphorylation and migration of LHCII-PSII to photosystem I (PSI) after transition to state 2 (red) light conditions, thus leading to the formation of PSI-PSII-LHCII and PSI-LHCII supercomplex to balance the relative excitation of PSI and PSII. Involved in the production of reactive oxygen species (ROS) and stomatal closure upon abscisic acid ( [...] (265 aa)
