Research Abstract

Reorganization of actin cytoskeleton and formation of actin rings in osteoclasts are necessary for bone-resorbing activity. Ror2, a receptor of Wnt5a, was expressed in osteoclasts. Ror2 deficient osteoclasts failed to form actin rings. Furthermore, we revealed that activation of Rho via Daam2 was required for actin ring formation downstream of Ror2.
