Recombinant Human IL5Ra / CD125 Protein (His tag)

Interleukin 5 receptor, alpha (IL5RA) also known as CD125 (Cluster of Differentiation 125) is a subunit of the Interleukin-5 receptor. IL5RA (CD125) is an interleukin 5 specific subunit of a heterodimeric cytokine receptor. The receptor is comprised of a ligand specific alpha subunit and a signal transducing beta subunit shared by the receptors for interleukin 3 (IL3), colony stimulating factor 2 (CSF2/GM-CSF), and interleukin 5 (IL5). The binding of this protein to IL5 depends on the beta subunit. The beta subunit is activated by the ligand binding, and is required for the biological activities of IL5. This protein has been found to interact with syndecan binding protein (syntenin), which is required for IL5 mediated activation of the transcription factor SOX4. Six alternatively spliced transcript variants encoding three distinct isoforms have been reported. IL5RA (CD125) is a T-cell-derived cytokine which is particularly important in the development of asthma for the lerminal differentiation, activation and survival of committed cosinophil precursors.

Species(s) : Human


Protein Expression Host : Human Cells


Protein Construction : A DNA sequence encoding the human IL5Ra isoform 2 (Q01344-2) (Met 1-Arg 335) was expressed, fused with a polyhistidine tag at the C-terminus.


Predicted N-terminal amino acid : Asp 21


Molecular weight/mass : The recombinant human IL5Ra consists of 326 amino acids after removal of the signal peptide and has a predicted molecular mass of 37.3 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhIL5Ra is approximately 45-50 kDa due to glycosylation.
