Integrin alphaVbeta3 is highly expressed on osteoclasts, bone resorbing cells and is upregulated during vascular damage, angiogenesis and certain type of malignancies. It binds to vitronectin by recognizing the conserved RGD sequence within the N-terminal region. Integrin alphaVbeta3 plays an important role in signal transduction and regulation of osteoclast function. The integrin alphaVbeta5 receptor also interacts with vitronectin, promoting cell spreading. Integrin alphaVbeta8 can bind vitronectin as well as fibrin.
