http://purl.uniprot.org/citations/20516062http://www.w3.org/2000/01/rdf-schema#comment"The cytokines, interleukin-3 (IL-3), interleukin-5 (IL-5), and granulocyte-macrophage colony-stimulating factor (GM-CSF), exhibit overlapping activities in the regulation of hematopoietic cells. In humans, the common beta (betac) receptor is shared by the three cytokines and functions together with cytokine-specific alpha subunits in signaling. A widely accepted hypothesis is that receptor activation requires heterodisulfide formation between the domain 1 D-E loop disulfide in human betac (hbetac) and unidentified cysteine residues in the N-terminal domains of the alpha receptors. Since the development of this hypothesis, new data have been obtained showing that domain 1 of hbetac is part of the cytokine binding epitope of this receptor and that an IL-3Ralpha isoform lacking the N-terminal Ig-like domain (the "SP2" isoform) is competent for signaling. We therefore investigated whether distortion of the domain 1-domain 4 ligand-binding epitope in hbetac and the related mouse receptor, beta(IL-3), could account for the loss of receptor signaling when the domain 1 D-E loop disulfide is disrupted. Indeed, mutation of the disulfide in hbetac led to both a complete loss of high affinity binding with the human IL-3Ralpha SP2 isoform and of downstream signaling. Mutation of the orthologous residues in the mouse IL-3-specific receptor, beta(IL-3), not only precluded direct binding of mouse IL-3 but also resulted in complete loss of high affinity binding and signaling with the mouse IL-3Ralpha SP2 isoform. Our data are most consistent with a role for the domain 1 D-E loop disulfide of hbetac and beta(IL-3) in maintaining the precise positions of ligand-binding residues necessary for normal high affinity binding and signaling."xsd:string
