NCIt definition : Interleukin-6 receptor subunit alpha (468 aa, 52 kDa) is encoded by the human IL6R
gene. This protein plays a role in regulation of the immune response, interleukin-6-mediated
signaling, and hematopoiesis.;
NCIt note : Interleukin 6 receptor subunit alpha contains an IgC2 domain, 2 FNIII cytokine-binding
domains, and a WSXWS motif for protein folding, intracellular transport, and cell-surface
receptor binding. A soluble IL6R may be released from the membrane by proteolysis.
The IL6R subunit of the IL6 receptor complex binds to the potent pleiotropic cytokine
IL6 with low affinity, but does not transduce a signal. Signal activation requires
association with IL6ST.;
