Background: IL-9R

The specific high affinity functional IL-9 receptor complex consists of a ligand-specific IL-9 R( alpha ) type I transmembrane subunit and the common gamma chain that is shared with the receptors for IL-2, IL-4, IL-7 and IL-15. Both the IL-9 R subunit and the common gamma chain are members of the hematopoietin receptor superfamily. Human and mouse IL-9 receptors share 53% amino acid sequence identity, and contain 468 and 533 amino acids, respectively. As a result of alternative splicing, cDNA clones encoding isoforms of IL-9 R, including a putative soluble form, have also been identified. Cells known to express IL-9 R include T cells, neutrophils, mast cells and macrophages.
