The invention relates to fusion proteins useful in delivering a targeted nucleic acid to a target cell, comprising a gene delivery fusion protein (GDFP), said GDFP comprising a nucleic acid binding domain (NBD) that binds to the targeted nucleic acid, fused to a gene delivery domain (GDD) that mediates delivery of the targeted nucleic acid to the target cell, wherein said GDD comprises one or more components that facilitate delivery of a targeted nucleic acid to a target cell, and wherein one of said components is a transport/localization component and wherein said transport/localization component is an adenovirus protein V or derivative thereof that retains protein V activity, and related methods of making and using thereof.
