CC -!- FUNCTION: Nuclear genome-encoded factor required for the accumulation
CC of photosystem I (PSI) during plant development. May form a complex
CC with PSAG and mediate thiol transactions in the thylakoid lumen that
CC are important for the assembly of PSI. Possesses protein-disulfide
CC reductase activity in vitro. {ECO:0000269|PubMed:25228689}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid lumen
CC {ECO:0000269|PubMed:25228689}.
CC -!- DISRUPTION PHENOTYPE: Slight pale green leaf phenotype.
CC {ECO:0000269|PubMed:25228689}.
