CC -!- FUNCTION: May be involved in non-photochemical quenching, a process
CC that maintains the balance between dissipation and utilization of light
CC energy to minimize generation of oxidizing molecules, thereby
CC protecting the plant against photo-oxidative damage (By similarity).
CC May play a photoprotective role in the thylakoid membrane in response
CC to light stress (Probable). {ECO:0000250|UniProtKB:Q9XF91,
CC ECO:0000305}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC {ECO:0000269|PubMed:10725357}; Multi-pass membrane protein
CC {ECO:0000255}.
CC -!- INDUCTION: Present at low levels under low light conditions, but
CC accumulates under high-intensity light. Induced by UV-A illumination.
CC Fades out upon wounding. {ECO:0000269|PubMed:10725357}.
CC -!- SIMILARITY: Belongs to the ELIP/psbS family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CAA17553.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
CC Sequence=CAB80136.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
