IL-5R alpha/CD125 Protein, Human, Recombinant (aa 21-335, His)

Catalog No. TMPJ-00267
Synonyms: IL-5R subunit alpha, IL5RA, CD125, IL-5 receptor subunit α, Interleukin-5 receptor subunit alpha, IL-5R-alpha, CDw125, IL-5 receptor subunit alpha, IL-5R subunit α, IL5R, IL-5RA, IL-5R-α, Interleukin-5 receptor subunit α

Interleukin-5 Receptor alpha (IL-5Rα, CD125) is a 60 kDa hematopoietin receptor that plays a dominant role in eosinophil biology. Mature human IL-5 Rα consists of a 322 aa extracellular domain (ECD) with a WSxWS motif and a four cysteine motif, a 20 aa transmembrane segment, and a 58 aa cytoplasmic domain. Within the ECD, human IL-5Rα shares 71% aa sequence identity with mouse and rat IL-5 Rα. Alternate splicing of human IL-5 Rα generates soluble secreted forms which function as IL-5 antagonists. The high affinity receptor for IL-5 is a complex that consists of the ligand binding IL-5 Rα and the transmembrane common β chain (βc/CD131) which is shared with the receptor complexes for IL-3 and GMCSF. IL-5 Rα binds IL-5 at low affinity and then associates with preformed βc oligomers to form the signaling competent receptor complex. IL-5 stimulation of CD34+ hematopoietic progenitor cells induces the up-regulation of transmembrane IL-5Rα followed by eosinophilic differentiation and activation.
