RT "A pigment-binding protein essential for regulation of photosynthetic light
RT harvesting.";
RL Nature 403:391-395(2000).
CC -!- FUNCTION: Plays an important role in non-photochemical quenching, a
CC process maintains the balance between dissipation and utilization of
CC light energy to minimize generation of oxidizing molecules, thereby
CC protecting the plant against photo-oxidative damage. Is not necessary
CC for efficient light harvesting and photosynthesis.
CC {ECO:0000269|PubMed:10667783}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC {ECO:0000269|PubMed:10667783}; Multi-pass membrane protein
CC {ECO:0000255}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=1;
CC Comment=A number of isoforms are produced. According to EST
CC sequences.;
CC Name=1;
CC IsoId=Q9XF91-1; Sequence=Displayed;
CC -!- DISRUPTION PHENOTYPE: Non-photochemical quenching phenotype.
CC {ECO:0000269|PubMed:10667783}.
CC -!- SIMILARITY: Belongs to the ELIP/psbS family. {ECO:0000305}.
