PF09240Interleukin-6 receptor alpha chain, binding (IL6Ra-bind)Interleukin-6 receptor alpha chain, bindingMembers of this family adopt a structure consisting of an immunoglobulin-like beta-sandwich, with seven strands in two beta-sheets, in a Greek-key topology. They are required for binding to the cytokine Interleukin-6 [1].Domain
