The ciliary neurotrophic factor receptor also known as CNTFR binds the ciliary neurotrophic factor. This receptor and its cognate ligand support the survival of neurons.^[1] This receptor is most closely related to the interleukin-6 receptor. This receptor possesses an unusual attachment to the cell membrane through a glycophosphatidylinositol linkage.^[2]

Model organisms have been used in the study of CNTFR function. A conditional knockout mouse line, called Cntfr^{tm1a(EUCOMM)Wtsi[7][8]} was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists.^[9][10][11]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.^[5][12] Twenty five tests were carried out on mutant mice and one significant abnormality was observed: no homozygous mutant animals were observed at weaning. The remaining tests were therefore carried out on adult heterozygous mutant animals, but no further abnormalities were seen. ^[5]
