[[http://www.uniprot.org/uniprot/ISIA_SYNY3 ISIA_SYNY3]] Functions as an antenna for photosystem I (PSI) under iron-limiting conditions, when phycobilisomes disappear. In the (PSI)3(Isi3)18 complex most of the harvested energy is probably used by PSI; in other PSI-containing supercomplexes a large part of the energy will probably not be used for light harvesting, but rather is dissipated to protect the organism from light damage.<ref>PMID:11507643</ref> <ref>PMID:16086587</ref> [[http://www.uniprot.org/uniprot/PSAE_SYNY3 PSAE_SYNY3]] Stabilizes the interaction between PsaC and the PSI core, assists the docking of the ferredoxin to PSI and interacts with ferredoxin-NADP oxidoreductase.[HAMAP-Rule:MF_00613]
