Function

Function:
Part of the receptor for interleukin 6. Binds to IL6 with low affinity, but does not transduce a signal. Signal activation necessitate an association with IL6ST. Activation may lead to the regulation of the immune response, acute-phase reactions and hematopoiesis.; Low concentration of a soluble form of IL6 receptor acts as an agonist of IL6 activity.
