In Brief
Hillebrand et al. found a novel family of RNA binding proteins that are targeted to Apicomplexan mitochondria. The proteins were named heptatricopeptide repeat (HPR) proteins, since they bear resemblance to plant organellar PPR and OPR proteins. These proteins are essential for parasite survival and are hypothesized to cause the accumulation of short mitochondrial RNA footprints, which were also discovered in the course of this work.
