Previous in vitro studies revealed that Jdp2 is involved in osteoclastogenesis. However, the
roles of Jdp2 in vivo and its pleiotropic functions are largely unknown. Here we generated
Jdp2–/–mice and discovered its crucial roles not only in bone metabolism but also in
differentiation of neutrophils. Jdp2–/–mice exhibited osteopetrosis resulting from impaired
osteoclastogenesis. Jdp2–/–neutrophils were morphologically normal but had impaired …
