Gene : MRL7 A. thaliana

DB identifier  ? AT4G28590 Secondary Identifier  ? locus:2139850
Name  ? Mesophyll-cell RNAi Library line 7 Brief Description  polyadenylate-binding protein 2-binding protein
TAIR Computational Description  polyadenylate-binding protein 2-binding protein;(source:Araport11)
TAIR Curator Summary  Encodes a dual-targeted nuclear/plastidial phytochrome signaling component required for PEP assembly. It controls PhAPG expression primarily from the nucleus by interacting with phytochromes and promoting their localization to photobodies for the degradation of the transcriptional regulators PIF1 and PIF3. RCB-dependent PIF degradation in the nucleus signals the plastids for PEP assembly and PhAPG expression.

MRL7_ARATH function Plays an essential role in early steps of chloroplast development (PubMed:21220584, PubMed:21515910, PubMed:23956074, PubMed:24111559, PubMed:33824329). 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:23956074, PubMed:24132784). 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, PubMed:21515910, PubMed:23956074, PubMed:24111559, PubMed:24132784). Participates in the early light signaling events of photobody biogenesis in chloroplasts (PubMed:31201314). May mediate the degradation of two repressors of chloroplast biogenesis, PIF1 and PIF3 in nucleus (PubMed:31201314). Collaboratively with PTAC12/HMR/PAP5, involved in the regulation of thermoresponsive responses via the stabilization of PIF4 in the daytime to initiate thermomorphogenesis (PubMed:33824329).
MRL7_ARATH subcellular location Associated with punctuate structures in chloroplasts.
MRL7_ARATH tissue specificity Expressed in leaves, shoots, stems, cauline leaves, flower buds, flowers and siliques.
