Peptide targeting moieties that target the cells of the inner ear can be used for targeted therapeutics. As such, nucleic acids and/or drugs can be associated with the targeting moieties in order to provide therapeutics that are delivered to specific cells in the inner ear. Conjugation of drugs or gene therapy vectors to cell specific peptides may allow the treatment of individual cell types within the inner ear. The peptide targeting moieties can be polypeptides having the sequences of Table 1 in an unnatural configuration. The polynucleotide can either consist of the sequence or include additional polypeptides attached to the ends of the sequences shown in Table 1. The polynucleotide can be in a non-native configuration. For example, the polypeptide is selected from the following: a-h-p-h-h-s-m (SEQ ID NO: 12)； h-p-h-h-r-i-f (SEQ ID NO: 29)； t-v-p-q-l-t-t (SEQ ID NO: 1)； s-t-t-k-l-a-l (SEQ ID NO: 2)； m-e-g-y-i-h-r (SEQ ID NO: 3)； h-a-i-y-p-r-h (SEQ ID NO: 5)； h-s-r-l-l-d-q (SEQ ID NO: 6)； i-q-s-p-h-f-f (SEQ ID NO: 7)； or y-a-a-h-r-s-h (SEQ ID NO: 8).
