摘要:

The invention provides an improved design for the construction of extensible nucleic acid-based, ligand-controlled regulatory systems, and the nucleic acid regulatory systems resulting therefrom. The invention contemplates improving the design of the switches (ligand-controlled regulatory systems) through the design of an information transmission domain (ITD). The improved ITD eliminates free-floating ends of the switching and the competing strands, and localizes competitive hybridization events to a contiguous strand of competing and switching strands in a strand-displacement mechanism-based switch, thereby improving the kinetics of strand-displacement. The improved regulatory systems have many uses in various biological systems, including gene expression control or ligand-concentration sensing.
