CC -!- FUNCTION: Required for non-photochemical quenching (NPQ), a mechanism
CC that converts and dissipates the harmful excess absorbed light energy
CC into heat and protect the photosynthetic apparatus from photo-oxidative
CC damage (PubMed:27358399, PubMed:27329221). Seems involved in the
CC activation of NPQ, possibly by promoting conformational changes
CC required for activation of LHCSR3-dependent quenching in the antenna of
CC photosystem II (PSII) (PubMed:27358399, PubMed:27329221).
CC {ECO:0000269|PubMed:27329221, ECO:0000269|PubMed:27358399}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC {ECO:0000305}; Multi-pass membrane protein {ECO:0000255}.
CC -!- INDUCTION: Induced transiently by high light stress (at protein level).
CC {ECO:0000269|PubMed:27329221, ECO:0000269|PubMed:27358399}.
CC -!- SIMILARITY: Belongs to the ELIP/psbS family. {ECO:0000305}.
