Binds to CNTF. The alpha subunit provides the receptor specificity (By similarity). Forms a heterotrimer with LIFR and IL6ST. Interacts with heterodimeric neurotropic cytokine composed of CLCF1/CLC and CRLF1/CLF-1. Either alone or in complex with the heterodimer CLCF1-CRLF1 interacts with SORL1; this interaction may promote internalization and lysosomal degradation. Expressed in retina, brain, spleen, lung, liver and kidney. In the retina it is highly expressed by photoreceptors, but also found in the RPE, inner nuclear layer and ganglion cells. 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.
