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, chloroplast thylakoid membrane
CC {ECO:0000255|HAMAP-Rule:MF_00439}; Peripheral membrane protein
CC {ECO:0000255|HAMAP-Rule:MF_00439}.
CC -!- RNA EDITING: Modified_positions=15 {ECO:0000269|PubMed:7545915}, 62
CC {ECO:0000269|PubMed:7545915}; Note=Editing is independent of both
CC splicing and processing of the primary transcript.;
CC -!- SIMILARITY: Belongs to the Ycf3 family. {ECO:0000255|HAMAP-
CC Rule:MF_00439}.
