Interleukin-6 receptor subunit alpha

Gene

Il6r

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

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.

Domaini

The two fibronectin type-III-like domains contained in the C-terminal part form together a cytokine-binding domain.
The WSXWS motif appears to be necessary for proper protein folding and thereby efficient intracellular transport and cell-surface receptor binding.
