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 -!- SUBUNIT: Interacts with ALB3.1, which is essential for its insertion
CC into thylakoid membrane. {ECO:0000269|PubMed:12215522}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC {ECO:0000250}; Peripheral membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the PsaE family. {ECO:0000305}.
