CC   -!- FUNCTION: Stabilizes the interaction between PsaC and the PSI core,
CC       assists the docking of the ferredoxin to PSI and interacts with
CC       ferredoxin-NADP oxidoreductase. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC       {ECO:0000269|PubMed:1374333}; Peripheral membrane protein
CC       {ECO:0000269|PubMed:1374333}.
CC   -!- SIMILARITY: Belongs to the PsaE family. {ECO:0000305}.
