Background: IL-3R alpha

Interleukin 3 is a pleiotropic cytokine produced primarily by activated T cells or mast cells. IL-3 stimulates the proliferation and differentiation of hemopoietic cells including the pluripotent hematopoietic stem cells as well as various lineage-committed cells. The biological effects of IL-3 on the various cell types are mediated by the binding of IL-3 to specific cell surface receptor complexes. The functional high-affinity human IL-3 receptor is a heterodimer consisting of a ligand binding alpha subunit and the beta subunit. The alpha subunit alone binds IL-3 with low affinity. The beta subunit does not bind IL-3 by itself but is required for the high-affinity binding of IL-3 to the heterodimeric receptor complex. The beta subunit has also been found to be a component of the high-affinity receptor complex for IL-5 and GM-CSF. Both the alpha and the beta subunits are members of the cytokine receptor superfamily.
