Description
RANK (Receptor Activator of Nuclear Factor κ B), also known as TRANCE Receptor is a type I membrane protein which is TNF receptor family member1 expressed on the surface of osteoclasts and is involved in the activation of osteoclasts upon ligand binding. It is also expressed on dendritic cells and facilitates immune signaling. RANK is highly expressed in mature osteoclasts.2 RANK is the intrinsic cell surface determinant that mediates osteoprotegerin ligand effects on bone resorption and remodeling as well as the physiological and pathological effects of calciotropic hormones and proresorptive cytokines.3
