The present invention is directed to Niemann-Pick disease, type C1 (NPC1) binding polypeptides and NPC1 binding peptide conjugates comprising these binding polypeptides. The present invention is further directed to pharmaceutical compositions comprising these NPC1 binding polypeptide and binding peptide conjugates and the use of these compositions to treat a variety of conditions, including cancer, infectious diseases, neurodegenerative diseases, inflammatory conditions, and bone conditions. The NPC1 binding conjugates are also useful for enhancing endosomal release of pharmaceutically active moieties. |
