Binds to CNTF (GPA). The alpha subunit provides the receptor specificity. Heterotrimer of the alpha subunit, LIFR and IL6ST. Highly expressed in nervous system. Also found in skeletal muscle. The WSXWS motif appears to be necessary for proper protein folding and thereby efficient intracellular transport and cell-surface receptor binding. Belongs to the type I cytokine receptor family. Type 3 subfamily.
