Insulin-like growth factors (IGFs) comprise a family of endocrine, paracrine and autocrine polypeptidesconsisting of the ligands IGF1 and IGF2, two receptors (IGF1R, IGF2R), at least 6 IGF-binding proteins (IGFBPs)and IGFBP proteases. Among the binding proteins, IGFBP6 is unique because of its N-terminal disulfide linkagesand its marked binding preference for IGF2. It is a potent inhibitor of the interaction between IGF2 and itsreceptor IGF1R, thus preventing major functions of IGF2, such as induction of proliferation, differentiation, celladhesion, or colony formation. In particular, IGFBP-6 inhibited the growth of neuroblastoma andrhabdomyosarcoma xenografts. GFBP-6 is expressed in many tissues, including lung, liver, gut and the centralnervous system.
