/Methods And Compositions To Spread Protein Cargoes Across Multi-nucleated Cells
Abstract

Methods and compositions useful for delivering a protein to a plurality of nuclei in a cell. Fusion proteins comprising one or more signals useful for promoting delivery of the proteins to a plurality of nuclei in a multinucleate cell. Methods comprising administering isolated nucleic acids to a multinucleate cell, wherein the isolated nucleic acid comprises a sequence encoding a fusion protein, the fusion protein comprising, a protein of interest fused to at least the following migration signals: (a) at least one nuclear export signal (NES); and (b) at least one nuclear localization signal (NLS) and/or at least one nucleolar localization signal (NoLS). Fusion proteins comprising: (a) a protein of interest; and (b) at least the following migration signals: (i) a nuclear export signal (NES); (ii) a nuclear localization signal (NLS); and (iii) a nucleolar localization signal (NoLS). Methods of making and using the same. Methods of delivering recombinant genes and/or fusion proteins to multinucleate cells.
