Research Abstract |
We have found that OPG, which is previously recognized as a decoy receptor for RANKL, forms a complex with RANKL at the Golgi apparatus and the complex formation is necessary for Vps33a-mediated RANKL sorting to the lysosomes in osteoblastic cells. We have also found that RANKL localized at the lysosomes relocate to the cell surface in response to RANK stimulation. These processes can be novel therapeutic targets for osteoporosis.
