LIF-R binds a cytokine that acts on many cell types including embryonic stem cells, megakaryocytes, osteoblasts, and neuronal cells. The extracellular region of this protein shows a modular structure with two cytokine-binding modules (CBM, with Pfam:PF17971 representing the second subdomain of CBM1, D2) separated by an Ig-like domain (this entry) and followed by three membrane- proximal fibronectin type-III (FNIII) domains (Pfam:PF00041) This domain interacts directly with site 3 of Cilliary Neutrophic Factor (CNTF) [1,2].

LIFR has an extracellular region with a modular structure containing two cytokine-binding modules (CBM) separated by an Ig-like domain and followed by three membrane-proximal fibronectin type-III (FNIII) domains. The D2 domain in CBM1 shows structural similarity to the corresponding CBM domains of both gp130 and IL-6Ralpha because it contains conserved structural features like the WSXWS motif [1] [2]. The WSXWS motif in cytokine receptors is a molecular switch involved in receptor activation [3].

LIFR is a cell surface receptor that mediates the actions of LIF and other interleukin-6 type cytokines through the formation of signalling complexes with gp130. This is the N-terminal domain, referred to as domain 1, which contains conserved disulfide bonds between Cys-10 to Cys-20 and Cys-37 to Cys-45 [1].
