NCIt definition : Leukemia inhibitory factor receptor (1097 aa, 124 kDa) is encoded by the human LIFR
gene. This protein is involved in leukemia inhibitory factor binding and ligand-dependent
signal transduction.;
NCIt note : Leukemia Inhibitory Factor (LIF), encoded by the LIF gene, is a polyfunctional cytokine
that affects the differentiation, survival, and proliferation of a wide variety of
cells in the adult and the embryo. LIF action is mediated through a high-affinity
receptor complex composed of Leukemia Inhibitory Factor Receptor (a low-affinity LIF
binding chain) and gp130 (a high-affinity converter subunit). The high-affinity complex
also binds oncostatin M, a related cytokine. Both Leukemia Inhibitory Factor Receptor
and gp130 are members of a family of cytokine receptors that includes components of
the receptors for the majority of hematopoietic cytokines and for cytokines that affect
other systems, including the ciliary neurotrophic factor, growth hormone and prolactin.;
