Kindlin-3–mediated signaling from multiple integrin classes is required for osteoclast-mediated bone resorption

Abstract excerpt

The blood cell-specific kindlin-3 protein is required to activate leukocyte and platelet integrins. In line with this function, mutations in the KINDLIN-3 gene in man cause immunodeficiency and severe bleeding. Some patients also suffer from osteopetrosis, but the underlying mechanism leading to abnormal bone turnover is unknown. Here we show that kindlin-3-deficient mice develop severe osteopetrosis because of...
