Enables ciliary neurotrophic factor receptor activity and cytokine binding activity. Predicted to be involved in ciliary neurotrophic factor-mediated signaling pathway. Predicted to act upstream of or within several processes, including brainstem development; negative regulation of neuron apoptotic process; and suckling behavior. Predicted to be located in apical plasma membrane. Predicted to be part of CNTFR-CLCF1 complex and ciliary neurotrophic factor receptor complex. Predicted to be active in external side of plasma membrane. Orthologous to human CNTFR (ciliary neurotrophic factor receptor). [provided by Alliance of Genome Resources, Apr 2022]
