Force regulated conformational change of integrin αVβ3.

Integrins mediate cell adhesion to extracellular matrix and transduce signals bidirectionally across the membrane. Integrin αVβ3 has been shown to play an essential role in tumor metastasis, angiogenesis, hemostasis and phagocytosis. Integrins can take several conformations, including the bent and extended conformations of the ectodomain, which regulate… (More)
