The effects and the mode of action of hypericin (1) were studied, in the dark, on the action potential (AP) and the L-type Ca2+ channel of frog atrial heart muscle, using intracellular microelectrode and patch-clamp techniques, respectively. In the p

RNA Silencing of Mitochondrial m-Nfs1 Reduces Fe-S Enzyme Activity Both in Mitochondria and Cytosol of Mammalian Cells

Autor: Marie-Jeanne Chauveau, Cécile Bouton, Blanche Guillon, Jean-Claude Drapier, Cédric Fosset, Frédéric Canal

Journal of Biological Chemistry, American Society for Biochemistry and Molecular Biology, 2006, 281(35), pp.25398-25406. ⟨10.1074/jbc.M602979200⟩

In prokaryotes and yeast, the general mechanism of biogenesis of iron-sulfur (Fe-S) clusters involves activities of several proteins among which IscS and Nfs1p provide, through cysteine desulfuration, elemental sulfide for Fe-S core formation. Althou

Recycling of RNA Binding Iron Regulatory Protein 1 into an Aconitase after Nitric Oxide Removal Depends on Mitochondrial ATP

Autor: Jean-Claude Drapier, Cécile Bouton, Marie-Jeanne Chauveau, Sylvie Lazereg

Publikováno v: Journal of Biological Chemistry. 277:31220-31227

Iron regulatory proteins (IRPs) control iron metabolism by specifically interacting with iron-responsive elements (IREs) on mRNAs. Nitric oxide (NO) converts IRP-1 from a [4Fe-4S] aconitase to a trans-regulatory protein through Fe-S cluster disassemb
