It participates in ...	GM-CSF/IL-3/IL-5 receptor common beta subunit (IL3RB) is a cell surface receptor that plays a role in immune response and controls the production and differentiation of haematopoietic progenitor cells into lineage-restricted cells. It participates in the signaling pathways of interleukin-3, interleukin-5 and granulocyte-macrophage colony-stimulating factor/CSF2 which have overlapping activities on haematopoietic cells [1-4] and have been implicated in the pathogenesis of allergic diseases of the lung. IL3RB consists of four extracellular domains with an Ig-like fold. This entry represents the first domain.	Domain
