Talin, a Rap1 effector for integrin activation at the plasma membrane, also promotes Rap1 activity by disrupting sequestration of Rap1 by SHANK3.

Talin regulates the adhesion and migration of cells in part by promoting the affinity of integrins for extracellular matrix proteins, a process that in cells such as endothelial cells and platelets requires the direct interaction of talin with both the small GTPase, Rap1-GTP, and the integrin β3 cytoplasmic tail. To study this process in more detail, we employed an optogenetic approach in living, immortalized endothelial cells to be able to regulate talin interaction with the plasma membrane. Previous studies identified talin as the Rap1-GTP effector for β3 integrin activation.
