CC   -!- FUNCTION: Seems to play a role in the dimerization of PSII (By
CC       similarity). Essential to maintain photosynthetic activity under
CC       adverse growth conditions. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane; Single-
CC       pass membrane protein.
CC   -!- SIMILARITY: Belongs to the PsbT family. {ECO:0000305}.
