Function
Plays an essential role in early steps of chloroplast development (PubMed:21220584, PubMed:21515910, PubMed:23956074, PubMed:24111559). Involved in the regulation of plastid gene expression (PubMed:21515910, PubMed:23956074, PubMed:24111559). May positively regulate plastid-encoded RNA polymerase (PEP) activity through binding to FSD3 and CITRX/TRXZ (PubMed:23956074). Involved in redox-mediated regulation of chloroplast development (PubMed:24132784, PubMed:23956074). Possesses disulfide reductase activity in vitro (PubMed:23956074). Required for the proper function of the plastid transcriptional machinery and protein accumulation in thylakoid membranes. May function as molecular chaperone to ensure proper organization of the nucleoids in chloroplasts (PubMed:24111559). May mediate some aspect of thylakoid structure or function that controls non-photochemical quenching (NPQ) (PubMed:21220584).
