CC   -!- FUNCTION: Seems to be involved 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. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC       {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the ELIP/psbS family. {ECO:0000305}.
