Cellular prion protein is present in mitochondria of healthy mice.
Scientific Reports 2017 Februrary 3
Cellular prion protein (PrPC ) is a mammalian glycoprotein which is usually found anchored to the plasma membrane via a glycophosphatidylinositol (GPI) anchor. PrPC misfolds to a pathogenic isoform PrPSc , the causative agent of neurodegenerative prion diseases. The precise function of PrPC remains elusive but may depend upon its cellular localization. Here we show that PrPC is present in brain mitochondria from 6-12 week old wild-type and transgenic mice in the absence of disease. Mitochondrial PrPC was fully processed with mature N-linked glycans and did not require the GPI anchor for localization. Protease treatment of purified mitochondria suggested that mitochondrial PrPC exists as a transmembrane isoform with the C-terminus facing the mitochondrial matrix and the N-terminus facing the intermembrane space. Taken together, our data suggest that PrPC can be found in mitochondria in the absence of disease, old age, mutation, or overexpression and that PrPC may affect mitochondrial function.
