Preparation and Storage

Background: LIFR alpha

Leukemia Inhibitory Factor Receptor alpha (LIF R alpha ), also known as LIFR beta and CD118, is a 190 kDa type I transmembrane protein in the Interleukin-6 receptor family. Members of this family mediate the biological effects of Cardiotrophin-1, CLC, CNTF, IL-6, IL-11, IL-27, and Oncostatin M (1). Mature mouse LIF R alpha consists of a 785 amino acid (aa) extracellular domain (ECD) with two cytokine receptor homology domains, one WSxWS motif, and three fibronectin type III repeats, followed by a 25 aa transmembrane segment and a 239 aa cytoplasmic domain (2, 3). Within the ECD, mouse LIF R alpha shares 73% and 90% aa sequence identity with human and rat LIF R alpha, respectively. Alternative splicing generates a 90 kDa soluble form of the mouse LIF R alpha ECD (4). LIF R alpha binds the pleiotropic cytokine LIF with low affinity, and the soluble isoform retains LIF-binding activity (5). Binding affinity is increased by the ligand-induced association of LIF R alpha with the signal transducing subunit gp130 (6, 7). The LIF R alpha /gp130 receptor complex also transduces Oncostatin M signals, although LIF R alpha alone does not interact with Oncostatin M (6). gp130 associates with different ligand-specific receptors to form signaling receptor complexes for the other IL-6 family ligands (1). The CNTF receptor is a ternary complex that contains CNTF R alpha and gp130 as well as LIF R alpha (8, 9). LIF R alpha is widely expressed, and LIF induces the proliferation, differentiation, and activation of cells in many tissues (10, 11). In particular, LIF R alpha plays an important role in several aspects of early pregnancy such as blastocyst implantation in the uterus (4, 12-14).
