[[http://www.uniprot.org/uniprot/THIO_ECO57 THIO_ECO57]] Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions (By similarity). [[http://www.uniprot.org/uniprot/ALB3_ARATH ALB3_ARATH]] Required for the insertion of some light harvesting chlorophyll-binding proteins (LHCP) into the chloroplast thylakoid membrane. Required for the insertion of LHCB1, LHCB4.1 and LHCB5 proteins into thylakoid membrane, while it is not required for insertion of proteins PsbX, PsbW and PsbY.<ref>PMID:10636840</ref> <ref>PMID:11524428</ref> <ref>PMID:11891220</ref> <ref>PMID:9165749</ref> [[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>
