CC -!- FUNCTION: Interacts with photosystem II (PSII) core complexes and
CC participates in the maintenance of normal PSII activity under
CC photoinhibitory stress. May protect against photodamage or stabilize
CC PSII under high-light stress (PubMed:25846821). Participates in the
CC maintainance of proper PSII function under high-light stress by
CC protecting PSII from photooxidative damage (PubMed:26337456).
CC {ECO:0000269|PubMed:25846821, ECO:0000269|PubMed:26337456}.
CC -!- SUBUNIT: Interacts with psbA, psbB, psbC and psbD.
CC {ECO:0000269|PubMed:25846821}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC {ECO:0000269|PubMed:25846821}; Single-pass membrane protein
CC {ECO:0000255}.
CC -!- DISRUPTION PHENOTYPE: Altered photosystem II (PSII) function under
CC high-irradiance light (PubMed:25846821). Elevated photodamage to PSII
CC reaction center proteins after high-light treatment (PubMed:26337456).
CC {ECO:0000269|PubMed:25846821, ECO:0000269|PubMed:26337456}.
