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:27335457, PubMed:29555769, PubMed:30782831). Is able to
CC sense luminal acidification of the thylakoid membranes, which occurs
CC along with elevated electron flow caused by excess light, and to induce
CC a large, fast, and reversible pH-dependent quenching in LHCII-
CC containing membranes (PubMed:27335457). Mediates excitation energy
CC transfer from light-harvesting complex II (LHCII) to photosystem I
CC (PSI), rather than photosystem II (PSII), at low pH, which mimics the
CC acidified lumen of the thylakoid membranes in high light-exposed
CC chloroplasts (PubMed:29555769, PubMed:30782831). Activates PSI-
CC dependent fluorescence quenching in addition to dissipating excitation
CC energy in LHCII to avoid photooxidative stress under excess light
CC (PubMed:29555769, PubMed:30782831). {ECO:0000269|PubMed:27335457,
CC ECO:0000269|PubMed:29555769, ECO:0000269|PubMed:30782831}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC {ECO:0000269|PubMed:10794530}; Multi-pass membrane protein
CC {ECO:0000255}.
CC -!- INDUCTION: Transiently induced by transition from dark to light (at
CC protein level) (PubMed:8980495, PubMed:10794530). Induced by high light
CC stress (at protein level) (PubMed:19940928, PubMed:24850838).
CC {ECO:0000269|PubMed:10794530, ECO:0000269|PubMed:19940928,
CC ECO:0000269|PubMed:24850838, ECO:0000269|PubMed:8980495}.
CC -!- SIMILARITY: Belongs to the light-harvesting chlorophyll a/b-binding
CC (LHC) protein family. {ECO:0000255|RuleBase:RU363080}.
