Background

IL-3 R is a heterodimeric structure composed of a 70 kDa IL-3 R alpha subunit (CD123) and a 120-140 kDa IL-3 R beta subunit (CD131). IL-3 R alpha binds IL-3 with relatively low affinity. In the presence of IL-3 R beta, however, IL-3 R alpha has a much higher affinity for IL-3. IL-3 is a pleiotropic cytokine that can stimulate proliferation and differentiation of pluripotent hematopoietic stem cells as well as various lineage committed progenitors. The IL-3 R alpha chain has a very short intracellular domain while the IL 3 R beta chain has a very large cytoplasmic domain. The IL 3 R beta chain is also shared by the receptors for IL-5 and GM-CSF. Cells known to express IL-3 receptors include hematopoietic progenitors, epithelial cells, double negative T cells, mast cells, basophils and blood monocytes.
