The interaction of insulin-like growth factors (IGFs) with insulin-like growth factor binding proteins (IGFBPs): a review

The original publication is available at www.springerlink.comThe interactions between insulin-like growth factor bindingproteins (IGFBPs) and insulin-like growth factors (IGFs)are important in regulating the availability of IGFs to thetype 1 IGF receptor (IGF1R) but there is still a lack ofinformation regarding the mechanism of IGF binding byIGFBPs. While many studies have defined general regions ofthe IGFBPs that interact with IGFs, only recently havespecific IGF binding residues been described. This reviewwill outline the structural evidence describing residues ofboth the IGFBPs and IGFs involved in the IGFBP-IGFinteraction.Francine E. Carrick, John C. Wallace and Briony E. Forbe
