CC -!- FUNCTION: May help in the organization of the PsaE and PsaF subunits.
CC {ECO:0000255|HAMAP-Rule:MF_00522}.
CC -!- SUBUNIT: PSI consists of a core antenna complex that captures photons,
CC and an electron transfer chain that converts photonic excitation into a
CC charge separation. The eukaryotic PSI reaction center is composed of at
CC least 11 subunits. Only detected in green leaves and not etioplasts;
CC PSI is only assembled in green leaves (PubMed:19137553).
CC {ECO:0000269|PubMed:19137553}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC {ECO:0000255|HAMAP-Rule:MF_00522, ECO:0000305|PubMed:19137553}; Single-
CC pass membrane protein {ECO:0000255|HAMAP-Rule:MF_00522,
CC ECO:0000305|PubMed:19137553}.
CC -!- SIMILARITY: Belongs to the PsaJ family. {ECO:0000255|HAMAP-
CC Rule:MF_00522}.
