PF09240 | Interleukin-6 receptor alpha chain, binding (IL6Ra-bind) | Interleukin-6 receptor alpha chain, binding | Members 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 | |
PF09238 | Interleukin-4 receptor alpha chain, N-terminal (IL4Ra_N) | Interleukin-4 receptor alpha chain, N-terminal | Members of this family are related in overall topology to fibronectin type III modules and fold into a sandwich comprising seven antiparallel beta sheets arranged in a three-strand and a four-strand beta-pleated sheet. They are required for binding o ... | Domain |
