Pet309 belongs to the pentatricopeptide repeat (PPR) protein family, which is involved in RNA metabolism in mitochondria and chloroplasts, and its sequence predicts at least 12 PPR motifs in the central portion of the protein. Deletion of these motifs selectively disrupted translation but not accumulation of the COX1 mRNA. We used RNA coimmunoprecipitation assays to show that Pet309 interacts with the COX1 mRNA in vivo and that this association is present before processing of the COX1 mRNA from the ATP8/6 polycistronic mRNA. This association was not affected by deletion of 8 of the PPR motifs but was undetectable after deletion of the entire 12-PPR region. However, interaction of the Pet309 protein lacking 12 PPR motifs with the COX1 mRNA was detected after overexpression of the mutated form of the protein, suggesting that deletion of this region decreased the binding affinity for the COX1 mRNA without abolishing it entirely. Moreover, binding of Pet309 to the COX1 mRNA was affected by deletion of Mss51. This work demonstrates an in vivo physical interaction between a yeast mitochondrial translational activator and its target mRNA and shows the cooperativity of the PPR domains of Pet309 in interaction with the COX1 mRNA."xsd:string |
