Structure of Resilin.

Resilin, an insect structural protein, exhibits rubberlike elasticity characterized by low stiffness, high extensibility, efficient energy storage, exceptional resilience, and fatigue lifetime. The outstanding mechanical properties of native resilin have motivated recent research about resilin-like biomaterials for a wide range of applications. The systematic understanding of the resilin structure provides theoretical guidance for its applications. In this chapter, we systematically introduce its special structure, providing useful information for the structure and elastic mechanism of native resilin protein.
