    摘要: The present invention provides, among other things, compositions and methods for treatment of Friedrich's Ataxia based on effective targeting of a therapeutic moiety to mitochondria that can substitute for natural FXN protein activity or rescue one or more phenotypes or symptoms associated with frataxin-deficiency. In some embodiments, the present invention provides a targeted therapeutic comprising a therapeutic moiety, which is a polypeptide having an N-terminus and a C-terminus, a mitochondrial targeting sequence associated with the therapeutic moiety at the N-terminus, and a mitochondrial membrane-penetrating peptide associated with the therapeutic moiety at the C-terminus, wherein the therapeutic moiety is targeted to mitochondria upon cellular entry.
