NCIt definition : Interleukin-4 receptor subunit alpha (825 aa, 90 kDa) is encoded by the human IL4R
gene. This protein plays a role in both interleukin-4 signaling and immunoglobulin
E production.;
NCIt note : Interleukin-4 receptor subunit alpha serves as the high-affinity interleukin 4 (IL4)
receptor when complexed with the cytokine receptor common subunit beta.; Interleukin-4 receptor subunit alpha can be cleaved to produce soluble interleukin-4
receptor subunit alpha (IL-4-binding protein). (UniProt);
