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:
a 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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

LHCSR3.2Light-harvesting complex stress-related protein 3.2, chloroplastic; Required for non-photochemical quenching (NPQ), a mechanism that converts and dissipates the harmful excess absorbed light energy into heat and protect the photosynthetic apparatus from photo-oxidative damage. NPQ includes dissipating excess light energy to heat (qE) and the reversible coupling of LHCII to photosystems (state transitions or qT), which are considered separate NPQ mechanisms. Is responsible for most of the excess light energy to heat dissipation (qE), also known as energy-dependent chlorophyll fluorescen [...] (259 aa)    
Predicted Functional Partners:
PSBS1
Photosystem II protein PSBS1; Required for non-photochemical quenching (NPQ), a mechanism that converts and dissipates the harmful excess absorbed light energy into heat and protect the photosynthetic apparatus from photo-oxidative damage. Seems involved in the activation of NPQ, possibly by promoting conformational changes required for activation of LHCSR3-dependent quenching in the antenna of photosystem II (PSII).
     
 0.916
LhcII-4
Chlorophyll a-b binding protein, 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; Belongs to the light-harvesting chlorophyll a/b-binding (LHC) protein family.
     
0.856
PSBS2
Photosystem II protein PSBS2; Required for non-photochemical quenching (NPQ), a mechanism that converts and dissipates the harmful excess absorbed light energy into heat and protect the photosynthetic apparatus from photo-oxidative damage. Seems involved in the activation of NPQ, possibly by promoting conformational changes required for activation of LHCSR3-dependent quenching in the antenna of photosystem II (PSII).

A8IB64_CHLRE
Stress related protein.
      
 0.831
PHOT
Phototropin; Protein kinase that acts as a blue light photoreceptor. Required for non-photochemical quenching (NPQ), a mechanism that converts and dissipates the harmful excess absorbed light energy into heat and protect the photosynthetic apparatus from photo-oxidative damage. Controls the energy-dependent chlorophyll fluorescence quenching (qE) activity of chlorophyll excited states by inducing the expression of the qE effector protein LHCSR3 in high light intensities.

Lhca1
Chlorophyll a-b binding protein, 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; Belongs to the light-harvesting chlorophyll a/b-binding (LHC) protein family.
  
  
 0.770
psaA
Photosystem I P700 chlorophyll a apoprotein A1; 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/cytochrome c6-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 or cytochrome c6.
     
 0.733
psbA
Photosystem II protein D1; This is one of the two reaction center proteins of photosystem II.
     
 0.716
PSBR
Photosystem II protein PSBR, chloroplastic; Associated with the oxygen-evolving complex of photosystem II (PSII) (Probable). Is required for the stable binding of LHCSR3 to PSII-LHCII supercomplexes and is essential for efficient energy- dependent quenching and the integrity of the PSII-LHCII-LHCSR3 supercomplex under continuous high light. Belongs to the psbR family.

LhcI-2
Chlorophyll a-b binding protein, 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; Belongs to the light-harvesting chlorophyll a/b-binding (LHC) protein family.
