The human IL-3, IL-5 and GM-CSF receptors are each composed of both unique a subunits and a common beta subunit. The a subunits are low affinity ligand binding proteins while the beta subunits do not themselves bind ligand, but are required for high affinity binding by the a subunits. In contrast, the mouse IL-3 receptor has two distinct beta subunits, one that functions only in IL-3 mediated cell signaling and a second that is shared with IL-5 and GM-CSF. The murine beta-subunits are 91% homologous at the amino acid level but only 56% homologous to the human beta subunit. Although neither the murine nor the human beta subunit contains tyrosine kinase domains, both activate tyrosine phosphorylation mediated signaling pathways.
The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is > 95% (by SDS-PAGE).
