The solution structure of the membrane proximal cytokine receptor domain of the human interleukin-6 receptor
Overview
The members of the interleukin-6-type family of cytokines interact with, receptors that have a modular structure and are built of several, immunoglobulin-like and fibronectin type III-like domains. These receptors, have a characteristic cytokine receptor homology region consisting of two, fibronectin type III-like domains defined by a set of four conserved, cysteines and a tryptophan-serine-X-tryptophan-serine sequence motif. On, target cells, interleukin-6 (IL-6) initially binds to its cognate, alpha-receptor and subsequently to a homodimer of the signal transducer, receptor gp130. The IL-6 receptor (IL-6R) consists of three extracellular, domains. The N-terminal immunoglobulin-like domain is not involved in, ligand binding, whereas the third membrane-proximal fibronectin-like, domain (IL-6R-D3) accounts for more than 90% of the binding energy to, IL-6. Here, we present the solution structure of the IL-6R-D3 domain, solved by multidimensional heteronuclear NMR spectroscopy.
