Predicted to enable several functions, including ciliary neurotrophic factor receptor activity; ciliary neurotrophic factor receptor binding activity; and scaffold protein binding activity. Predicted to contribute to cytokine receptor activity; growth factor binding activity; and interleukin-6 receptor binding activity. Involved in several processes, including interleukin-6-mediated signaling pathway; negative regulation of cytosolic calcium ion concentration; and triglyceride mobilization. Located in neuronal cell body membrane. Biomarker of brain ischemia; hepatocellular carcinoma; status epilepticus; and visual epilepsy. Human ortholog(s) of this gene implicated in arteriosclerosis; hyper IgE recurrent infection syndrome 4; and hyperandrogenism. Orthologous to human IL6ST (interleukin 6 cytokine family signal transducer). [provided by Alliance of Genome Resources, Apr 2022]
