CC   -!- FUNCTION: May help in the organization of the PsaE and PsaF subunits.
CC       {ECO:0000255|HAMAP-Rule:MF_00522}.
CC   -!- SUBCELLULAR LOCATION: Plastid membrane {ECO:0000305}; Single-pass
CC       membrane protein {ECO:0000255|HAMAP-Rule:MF_00522}.
CC   -!- SIMILARITY: Belongs to the PsaJ family. {ECO:0000255|HAMAP-
CC       Rule:MF_00522}.
CC   -!- CAUTION: Young tissue from this organism is photosynthetic and contains
CC       some thylakoids, although the photosynthetic activity does not exceed
CC       the light compensation point. {ECO:0000305}.
