CD131, also known as CSF2RB (colony-stimulating factor-2 receptor beta), IL3RB and IL5RB (IL-3/IL-5 receptor common beta), is a single pass, type I transmembrane glycoprotein of the type I cytokine receptor family, type 4 subfamily.  CD131 consists of a extracellular region with 2 fibronectin type III (FN3) domains and a juxtamembrane WSXWS motif, a transmembrane domain, and a cytoplasmic tail with the box 1 motif.  The WSXWS motif is necessary for proper protein folding and efficient intracellular transport and cell-surface receptor binding, while the box 1 motif is required for JAK interaction/activation. CD131 is a common beta chain of the high affinity receptor for IL-3, IL-5 and CSF to mediate their cellular responses.  For example, the CSF receptor complex is composed of a cytokine-specific alpha- chain CD116 and a beta-chain CD131 that are shared with the receptors for IL-3 and IL-5. CD116 alone binds GM-CSF with low affinity, whereas CD131 does not bind GM-CSF by itself. Association with CD131 converts CD116 from a low affinity to a high affinity receptor for GM­CSF. GM­CSF is a hematopoietic cytokine that regulates differentiation, survival, and proliferation of colony-forming unit-granulocyte-macrophage progenitor cells. Mutations in CD131 may cause pulmonary surfactant metabolism dysfunction 5 (SMDP5).
