Described is a construct comprising (a) a targeting moiety; (b) a fusogenic moiety consisting one or more fusogenic sequence(s) derived from dengue virus glycoprotein E comprising the sequence DRGWGNGCGLFGKGGI (SEQ ID NO:1 ) or a sequence which shows 1 to 8 substitutions, deletions, or insertions in comparison to SEQ ID NO:1; and (c) a molecule which is to be delivered into the cytoplasm of a cell. Moreover, described is a pharmaceutical composition comprising the construct according to the invention and optionally a pharmaceutical acceptable carrier. Further, described is a kit comprising one or more fusogenic sequence(s) derived from dengue virus glycoprotein E comprising the sequence as shown in SEQ ID NO:1 or a sequence which shows 1 to 8 substitutions, deletions, or insertions in comparison to SEQ ID NO:1. Further, described is the use of one or more fusogenic sequence(s) derived from dengue virus glycoprotein E for use in delivery of a therapeutic moiety, a detectable moiety, a nucleic acid molecule, preferably an siRNA, a carrier molecule, preferably a nanoparticle, a liposome and a viral vector into the cytoplasm of a cell. |
