An interaction between integrin and the talin FERM domain mediates integrin activation but not linkage to the cytoskeleton

Guy Tanentzapf & Nicholas H. Brown

Transmembrane adhesion receptors, such as integrins, mediate cell adhesion by interacting with intracellular proteins that connect to the cytoskeleton. Talin, one such linker protein, is thought to have two roles: mediating inside-out activation of integrins, and connecting extracellular matrix (ECM)-bound integrins to the cytoskeleton.
