... The N-terminal part of TIMPs is involved in binding to the active site of MMPs and hence prevents their action, whereas the C-terminal part can bind to proteins in the cell mem- brane and modulate ... associated inhibitor of MMP-2 that is able to inhibit the second activation step of MMP-2 [9]. The small calcium- binding protein S100A4 has been shown to regulate expre...

... conformational change in the extracellular domain, leading to an increase in affinity, thereby promoting integrin–ligand interactions [2]. In turn, clustering of integrins gene- rates a series of intracellular ... integrin activation, in view of the critical role of integrins in mediating adhesion and cell spreading. To address this, experiments were designed to compa...
