The conserved CDC motif in the yeast iron regulator Aft2 mediates iron-sulfur cluster exchange and protein-protein interactions with Grx3 and Bol2
Title: The conserved CDC motif in the yeast iron regulator Aft2 mediates iron-sulfur cluster exchange and protein-protein interactions with Grx3 and Bol2.
Comparative affinity assays indicated that the interaction between Fra2 and Aft2 is much stronger than that between Grx3 and Aft2, or Aft2 toward its target DNA. Aft2 activity seems to be regulated by Grx3.
Title: Structural and Biochemical Insights into the Multiple Functions of Yeast Grx3.
the absence of Aft2 leads to enhanced Pho90 function, involving both Spl2-dependent and independent events and resulting in selenite hyperaccumulation and toxicity.
Title: The yeast Aft2 transcription factor determines selenite toxicity by controlling the low affinity phosphate transport system.
Two Aft2 monomers bind a [2Fe-2S] cluster (or Fe2+) through a Cys-Asp-Cys motif, leading to dimerization of Aft2 and decreased DNA-binding affinity.
Title: Molecular mechanism and structure of the Saccharomyces cerevisiae iron regulator Aft2.
Aft2 activates the transcription of genes involved in intracellular iron use in the absence of Aft1.
Title: Direct activation of genes involved in intracellular iron use by the yeast iron-responsive transcription factor Aft2 without its paralog Aft1.
Aft1/Aft2 activation of the iron regulon depends on mitochondrial but not cytosolic iron-sulfur protein biogenesis
Title: Activation of the iron regulon by the yeast Aft1/Aft2 transcription factors depends on mitochondrial but not cytosolic iron-sulfur protein biogenesis.
