Background: IL-11 R alpha

Human interleukin 11 receptor alpha (IL-11 R alpha) is 150 kDa type I transmembrane protein in the hematopoietin cytokine receptor family that was cloned on the basis of its conserved WSXWS motif. IL-11 R alpha cDNA encodes a 422 amino acid (aa) residue precursor type I membrane protein, containg a signal peptide followed by extracellular (ECD), transmembrane and cytoplasmic domains. The extracellular region which is closely related to that of IL-6 R alpha and CNTF R alpha contains an immunoglobulin-like domain and two fibronectin-type III-like domains. Within the ECD, human IL-11 R alpha shares 85% and 83% aa sequence identity with mouse and rat IL-11 R alpha, respectively (1‑3). Alternate splicing generates an isoform of human IL-11 R alpha which lacks the cytoplasmic domain. By itself, IL-11 R alpha binds IL-11 with low affinity. IL-11 R alpha, together with gp130, forms a functional high-affinity receptor complex for IL-11. The expression of IL-11 R alpha has been detected in all adult tissues examined (lung, stomach, intestine), during embryonic development and in totipotent and differentiating embryonic stem cells. Recombinant soluble IL-11 R alpha has been shown to mediate IL-11 responsiveness in cells expressing the gp130 molecule. In cells expressing transmembrane IL-11 R alpha and gp130, soluble IL-11 R alpha has been shown to act as an IL-11 antagonist (3‑6).
