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: The cyanobacterial PSI reaction center is composed of one copy
CC each of PsaA,B,C,D,E,F,I,J,K,L,M and X, and forms dimeric and
CC tetrameric complexes. {ECO:0000269|PubMed:24550276}.
CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane
CC {ECO:0000269|PubMed:24550276}; Peripheral membrane protein
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the PsaE family. {ECO:0000305}.
