Thioredoxin-like fold domain-containing protein MRL7L, chloroplastic

UniProtKB accession:  Q9SKB6

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Plays an essential role in early steps of chloroplast development (PubMed:21515910, PubMed:24111559). Involved in the regulation of plastid gene expression (PubMed:21515910, PubMed:24111559). Required for the proper function of the plastid transcriptional machinery and protein accumulation in thylakoid membranes (PubMed:21515910, PubMed:24111559). May function as molecular chaperone to ensure proper organization of the nucleoids in chloroplasts (PubMed:21515910, PubMed:24111559). Is a necessary component of phytochrome signaling for photosynthesis-associated plastid-encoded genes (PhAPGs) activation (PubMed:31201314). Mediates the degradation of two repressors of chloroplast biogenesis, PIF1 and PIF3 in nucleus (PubMed:31201314). Promotes the assembly of the plastid-encoded RNA polymerase (PEP) complex for PhAPG transcription in plastids (PubMed:31201314).
