CC   -!- FUNCTION: Essential for the assembly of the photosystem I (PSI)
CC       complex. May act as a chaperone-like factor to guide the assembly of
CC       the PSI subunits. {ECO:0000255|HAMAP-Rule:MF_00439}.
CC   -!- SUBCELLULAR LOCATION: Plastid membrane {ECO:0000305}; Peripheral
CC       membrane protein {ECO:0000255|HAMAP-Rule:MF_00439}.
CC   -!- SIMILARITY: Belongs to the Ycf3 family. {ECO:0000255|HAMAP-
CC       Rule:MF_00439}.
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}.
