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:0000255|HAMAP-Rule:MF_00613}.
CC   -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00613}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_00613}.
CC   -!- SIMILARITY: Belongs to the PsaE family. {ECO:0000255|HAMAP-
CC       Rule:MF_00613}.
