[[http://www.uniprot.org/uniprot/SR43C_ARATH SR43C_ARATH]] Component of the chloroplast signal recognition particle pathway. Required for post-translational targeting of proteins into the tylakoid membrane but seems to be dispensable for co-translational targeting with a translating ribosome present. May be able to function independently of cpFTSY and FFC/cpSRP54 in targeting LHCPs to the thylakoids. Acts as a highly specific chaperone for LHCPs, preventing aggregation and being able to dissolve aggregates.<ref>PMID:9878634</ref> <ref>PMID:10480939</ref> <ref>PMID:15292240</ref> <ref>PMID:17513500</ref> <ref>PMID:20498370</ref>  [[http://www.uniprot.org/uniprot/SR54C_ARATH SR54C_ARATH]] Involved in cotranslational and post-translational sorting of thylakoid proteins. Binds GTP specifically. Activates the GTPase activity of CPFTSY when bound together. Required for light-harvesting chlorophyll a/b-binding protein (LHCP) integration into thylakoids.<ref>PMID:10480939</ref> <ref>PMID:11356852</ref> <ref>PMID:17475780</ref> <ref>PMID:18633119</ref>
