Abstract

Methods, systems, compositions and strategies for the delivery of WW domain-containing fusion proteins into cells in vivo, ex vivo, or in vitro via ARMMs are provided. Methods, systems, compositions and strategies for the delivery of Cas9 proteins and/or Cas9 variants into cells in vivo, ex vivo, or in vitro via fusion to ARMM associated proteins (e.g., ARRDC1 or TSG101) are also provided.
