Recombinant Mouse IL3RA Protein (Ser17-Lys331), C-hFc-tagged
Product Description
Cat
IMP-10453
Official Symbol
Il3ra
Product Overview
Recombinant Mouse IL-3R alpha/CD123 protein (Ser17-Lys331) with a Human IgG1 (Pro100-Lys330) Fc tag at C-terminus was expressed in Sf 21 cells.
Description
The protein encoded by this gene is an interleukin 3 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 IL3 depends on the beta subunit. The beta subunit is activated by the ligand binding, and is required for the biological activities of IL3. This gene and the gene encoding the colony stimulating factor 2 receptor alpha chain (CSF2RA) form a cytokine receptor gene cluster in a X-Y pseudoautosomal region on chromosomes X or Y. Alternatively spliced transcript variants encoding distinct isoforms have been found.
