A 317‐amino acid peptide, member of the tumor necrosis factor (TNF) superfamily, that stimulates osteoclast differentiation and activity as well as inhibiting osteoclast apoptosis. It is expressed by osteoblast‐stromal cells, fibroblasts, and activated T cells. In the bone tissue, RANKL binds directly to its receptor (i.e., receptor activator of nuclear factor‐kappa B [RANK]) on the…
