Description_x000D_ General description_x000D_ Tumor necrosis factor (ligand) superfamily, member 11 (Tnfsf11) is also known as receptor activator of nuclear factor-κB ligand (RANKL). It is a type II transmembrane signaling receptor. It has a molecular weight of around 35kDa. This protein contains an amino-terminal intracellular tail and a carboxy-terminal extracellular region, that bears a connecting stalk and a receptor-binding domain. Tnfsf11 is located on human chromosome 13q14.11._x000D_ Application_x000D_ RANK Ligand/TRANCE human can be used in in vitro osteoclastogenic assays for osteoclast differentiation._x000D_ RANK Ligand/TRANCE human has been used to stimulate differentiation._x000D_ Biochem/physiol Actions_x000D_ RANK Ligand (receptor activator of NF-kB ligand (RANKL) also referred to as TNF-related activation induced cytokines (TRANCE) or osteoprotegerin ligand is a protein that belongs to tumor necrosis factor (TNF) family. It stimulates the mature dendritic cells and induces the cytokine production. RANKL also facilitates bone remodelling and possess an angiogenic activity._x000D_ RANK Ligand/TRANCE, a member of the TNF superfamily, induces activation of the c-jun N-terminal kinase, enhances T-cell growth and dendritic cell function, induces osteoclastogenesis, and lymph node organogenesis. Mouse and human RANK Ligand share 85% amino acid identity. RANK is the cell surface receptor for RANK Ligand._x000D_ Physical form_x000D_ Lyophilized from a 0.2 μm filtered solution in 20 mM MOPS and 500 mM NaCl, pH 6.5, with 50 μg BSA per 1 μg as a carrier protein._x000D_ Analysis Note_x000D_ The biological activity is measured by its ability to induce osteoclast differentiation on mouse splenocytes.
