Abstract

The present invention relates to a recombinant protein for siRNA delivery, which allows the efficient intracellular and in vivo delivery of siRNA. More particularly, the present invention relates to a recombinant protein that allows a siRNA binding protein to be located in the interior cavity of a capsid protein of HBV (Hepatitis B virus), in which siRNAs of interest bind to the siRNA binding protein to be encapsulated within the capsid shell, thereby providing stability against the external attack such as nucleases and achieving the efficient intracellular and in vivo delivery of siRNA by its release into the cytosolic space after cell uptake.
