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.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid lumen.
CC   -!- SIMILARITY: Belongs to the PsaF family. {ECO:0000305}.
