ALLOSTERIC MODULATION Modular Switches

Many proteins behave like complex switches, integrating multiple inputs to control downstream outputs. It has been thought that such switches could evolve through recombination of their modular domains. Dueber et al. demonstrate this principle by showing that the actin-polymerizing activity of neuronal Wiskott-Aldrich syndrome protein (WASP) can be reprogrammed to respond to unnatural input by replacing input domains with heterologous ones. Achieving switch diversity through this process could underlie the evolution of signaling circuits.
