The Pet309 pentatricopeptide repeat motifs mediate efficient binding to the mitochondrial COX1 transcript in yeast.

RNA biology - 1 Jan 2014

Zamudio-Ochoa Angélica, Camacho-Villasana Yolanda, García-Guerrero Aldo E, Pérez-Martínez Xochitl

Abstract excerpt

Mitochondrial synthesis of Cox1, the largest subunit of the cytochrome c oxidase complex, is controlled by Mss51 and Pet309, two mRNA-specific translational activators that act via the COX1 mRNA 5'-UTR through an unknown mechanism. 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...
