CC   -!- FUNCTION: Probably participates in efficiency of electron transfer from
CC       plastocyanin to P700 (or cytochrome c553 in algae and cyanobacteria).
CC       This plastocyanin-docking protein contributes to the specific
CC       association of plastocyanin to PSI (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC       {ECO:0000305}; Single-pass membrane protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the PsaF family. {ECO:0000305}.
