RANK LIGAND FROM MOUSE RECOMBINANT EXPRESSED IN ESCHERICHIA COLI

General description

Tumor necrosis factor (ligand) superfamily, member 11 (Tnfsf11) or receptor activator of nuclear factor-κB ligand (RANKL) is a type II transmembrane signaling receptor. It has a molecular weight of about 35kDa. The protein possesses an amino-terminal intracellular tail and a carboxy-terminal extracellular region, which has a connecting stalk and a receptor-binding domain.

Application

RANK ligand from mouse has been used to visualize differentiated osteoclasts and to stimulate osteoclast differentiation.

The functions of RANK Ligand include induction of activation of the c-jun N-terminal kinase, enhancement of T cell growth and dendritic cell function induction of osteoclastogenesis, and lymph node organogenesis.The cell surface signaling receptor of RANK Ligand is RANK, which undergoes receptor clustering during signal transduction.

Biochem/physiol Actions

Tumor necrosis factor (ligand) superfamily, member 11 (Tnfsf11) or RANKL has an important role in osteoclast function and differentiation. It binds to RANK and osteoprotegrin (OPG). Bioactivities of RANKL may be attributed to its binding to these two receptor molecules. Mouse and human RANKL share 85% amino acid sequence identity.

Physical form

Lyophilized from a 0.2 μm filtered solution of 5 mM sodium phosphate, pH 7.6, and 75 mM NaCl.

Analysis Note

The bioactivity is determined by its ability to induce osteoclast differentiation of RAW 264.7. The expected ED₅₀ for this effect is ≤10 ng/ml.
