Abstract

Cell adhesion proteins play essential roles in the formation, regeneration, and maintenance of tissue. However, the molecular mechanisms by which cells regulate the conformation and binding properties of adhesion proteins are poorly understood. These biophysical properties can be resolved, with single-molecule resolution, using atomic force microscopy (AFM). Here, we outline how AFM force measurements can be used to study the conformation, cytoskeletal linkage, binding strength, and force-dependent bond lifetimes of adhesion proteins in live cells.
