products categories :
Receptors CD
products description :
CD123 is an subunit of a heterodimer IL-3 receptor, a member of the cytokine receptor superfamily. It is a 70 kDa protein, which binds IL-3 with high specificity but with low affinity. CD123 is encoded by the IL-3a gene, located in the pseudo-autosomal region (PAR) at the ends of the short arms of the X and Y chromosomes, B-lymphoid blasts from acute lymphoblastic leukemia (ALL) have been shown to express functional CD123 and CD40 ligand stimulates proliferation of precursor-B (pre-B) ALL by upregulating CD123 expression.

ncbi summary :
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. [provided by RefSeq, Jun 2012]
