Role of copper transporters in copper homeostasis.
Copper is a redox active metal that is essential for biological function. Copper is potentially toxic; thus, its homeostasis is carefully regulated through a system of protein transporters. Copper is taken up across the lumen surface of the small intestinal microvilli as cuprous ion by Ctr1. Cupric ion may also be taken up, but those processes are less well understood. Within the cell, intestin...
متن کاملTwo P-type ATPases are required for copper delivery in Arabidopsis thaliana chloroplasts.
Copper delivery to the thylakoid lumen protein plastocyanin and the stromal enzyme Cu/Zn superoxide dismutase in chloroplasts is required for photosynthesis and oxidative stress protection. The copper delivery system in chloroplasts was characterized by analyzing the function of copper transporter genes in Arabidopsis thaliana. Two mutant alleles were identified of a previously uncharacterized ...
متن کاملTranscriptional Regulation of Ribosome Components Are Determined by Stress According to Cellular Compartments in Arabidopsis thaliana
Plants have to coordinate eukaryotic ribosomes (cytoribosomes) and prokaryotic ribosomes (plastoribosomes and mitoribosomes) production to balance cellular protein synthesis in response to environmental variations. We identified 429 genes encoding potential ribosomal proteins (RP) in Arabidopsis thaliana. Because cytoribosome proteins are encoded by small nuclear gene families, plastid RP by nu...
متن کاملModulation of copper deiciency responses by diurnal and circadian rhythms in Arabidopsis thaliana
Copper homeostasis under deiciency is regulated by the SQUAMOSA PROMOTER BINDING PROTEIN-LIKE7 (SPL7) transcription factor. The daily oscillating expression of two SPL7-dependent copper deiciency markers, COPPER TRANSPORTER (COPT2) and IRON SUPEROXIDE DISMUTASE (FSD1), has been followed by quantitative PCR and in promoter:LUCIFERASE transgenic plants. Both genes showed circadian and diurnal reg...
