The role of single-protein elasticity in mechanobiology

Abstract

In addition to biochemical signals and genetic considerations, mechanical forces are rapidly emerging as a master regulator of human physiology. However, the molecular mechanisms that regulate force-induced functionalities across a wide range of scales, encompassing the cell, tissue or organ levels, are not well understood in comparison. With the advent, development and refining of single-molecule nanomechanical techniques that enable the conformational dynamics of individual proteins under the effect of a calibrated force to be probed, we have begun to acquire a comprehensive knowledge of the diverse physicochemical principles that regulate the elasticity of single proteins. Here, we review the major advances underpinning our current understanding of how the elasticity of single proteins regulates mechanosensing and mechanotransduction. We discuss the present limitations and future challenges of this prolific and burgeoning field.
