Cooperation of Two mRNA-Binding Proteins Drives Metabolic Adaptation to Iron Deficiency

2008

Summary Iron (Fe) is an essential cofactor for a wide range of cellular processes. We have previously demonstrated in yeast that Cth2 is expressed during Fe deficiency and promotes degradation of a battery of mRNAs leading to reprogramming of Fe-dependent metabolism and Fe storage. We report here that the Cth2-homologous protein Cth1 is transiently expressed during Fe deprivation and participates in the response to Fe deficiency through the degradation of mRNAs primarily involved in mitochondrially localized activities including respiration and amino acid biosynthesis. In parallel, wild-type cells, but not cth1 Δ cth2 Δ cells, accumulate mRNAs encoding proteins that function in glucose impo…
