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: Cellular thylakoid membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00439}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_00439}.
CC   -!- SIMILARITY: Belongs to the Ycf3 family. {ECO:0000255|HAMAP-
CC       Rule:MF_00439}.
