| + | Activation of cell surface receptor integrin has been extensively studied as the first key step to trigger cell adhesion, but the subsequent events, widely regarded as integrin "outside-in" signaling to form supramolecular complexes (focal adhesions [FAs]) to promote dynamic cell adhesion, remain poorly elucidated. Integrin activator kindlin-2 was recently found to associate with paxillin in nascent FAs, implicating an early yet undefined integrin outside-in signaling event. Here we show structurally that kindlin-2 recognizes paxillin via a distinct interface involving the ubiquitin-like kindlin-2 F0 domain and the paxillin LIM4 domain. The interface is adjacent to the membrane binding site of kindlin-2 F0, suggesting a mechanism for kindlin-2 to recruit paxillin to the membrane-proximal site where FA assembly is initiated. Disruption of the interface impaired the localization of paxillin, causing strong defects in FA assembly and cell migration. These data unveil a structural basis of the kindlin-2/paxillin interaction in controlling dynamic cell adhesion. | ||
