A new synthetic biology engineering strategy integrating chemical reactivity sensing and small molecule induced protein dimerization has been developed to generate artificial Fe2+ signaling circuitry to control tailored cellular events in mammalian cells. The dual function probe ABA-FE18 (Fe2+-sensing and protein dimerization) derived from ABA was developed and used to control gene activation, signal transduction, and cytoskeletal remodeling in response to Fe2+. This technology was utilized to design signal circuitry incorporating "AND" and "OR" biologic gates that enables mammalian cells to translate different combinations of Fe2+ and H2O2 signals into predefined biological outputs.
