Abstract
- Utilizing ultrasound as an external stimulus to remotely modulate the activity of proteins is an important aspect of sonopharmacology and establishes the basis for the emerging field of sonogenetics. Here, we describe an ultrasound-responsive protein splicing system that enables spatiotemporal control of split-intein-mediated protein ligation. The system utilizes engineered split inteins that are caged and can be activated by thrombin released from a high molar mass DNA-based carrier under focused ultrasound sonication. This approach represents a general method for controlling the functions of proteins of interest by ultrasound, as demonstrated here by the controlled synthesis of the superfolder green fluorescence protein (GFP) and calcitonin. Furthermore, calcitonin receptor-mediated signal transduction in cells was triggered by this system in vitro without harming cell viability. By expanding the sonogenetic toolbox with protein splicing technologies, this study provides a possible pathway to deploy ultrasound for remotely controlling a variety of protein functions in deep tissue in the future.
