Ectodomain shedding of receptor activator of NF-kappaB ligand

Abstract

Receptor activator of NF-kappab ligand (RANKL), a key regulator of osteoclastogenesis, is proteolytically processed and converted to a soluble form. RANKL sheddase and the biologic and pathologic role of RANKL shedding have been undetermined, but the identity of sheddase and its effect on osteoclastogenesis are gradually clarified. The regulatory mechanism and its relevance to some pathologic conditions are to be elucidated.
