RANKL and RANK are members of the TNF superfamily of ligands and receptors that play an important role in the regulation of specific immunity and bone turnover. RANK (receptor) was originally identified as a dendritic-cell-membrane protein, which by interacting with RANKL augments the ability of dendritic cells to stimulate naïve T cell proliferation and to promote the survival of RANK + T cells. RANK is also expressed in a variety of tissues including skeletal muscle, thymus, liver, colon, small intestine and adrenal gland. The RANK/RANKL interaction is important in the regulation of osteoclastogenesis and in dendritic-cell-mediated T cell immune responses. Impairments in RANK signaling have been implicated in the induction of expansive osteolysis and Paget disease of bone (PDB2). Recombinant rat sRANKL is a polypeptide comprising the TNF homologous region of RANKL (174aa residues).||Source:|Recombinant protein corresponding to 174aa residues from rat sRANK Ligand, expressed in E. coli. ||Molecular Weight: |~19.4kD||Biological Activity:|Determined by its ability to induce NFkappaB in RAW264.7 cells in the absence of any cross- linking.
