CD213A2,CT19,IL-13R,IL13BP

Catalog Number P10350-H03H
Organism Species Human
Host Human Cells
Synonyms CD213A2,CT19,IL-13R,IL13BP
Molecular Weight The recombinant human IL13Rα2/Fc is a disulfide-linked homodimeric protein after proteolytic removal of the signal peptide. The reduced monomer consists of 563 amino acids and predicts a molecular mass of 65 kDa. As a result of glycosylation, the rh IL13Rα2/Fc monomer migrates as an approximately 90-100 kDa band in SDS-PAGE under reducing conditions.
predicted N Asp 27
SDS-PAGE
Purity > 75 % as determined by SDS-PAGE
Protein Construction A DNA sequence encoding the extracellular domain of human IL13Rα2 (NP_000631.1) (Met 1-Leu 342) was fused with the C-terminal polyhistidine-tagged Fc region of human IgG1 at the C-terminus.
Bio-activity Measured by its binding ability in a functional ELISA. Immobilized recombinant human IL13RA2 at 8 μg/ml (100 μl/well) can bind IL13 with a linear range of 0.25-8.0 ng/ml .

Background Interleukin-13 receptor subunit alpha-2 (IL13RA2/IL-13RA2) is also known as also known as cluster of differentiation 213A2 (CD213A2), IL-13 receptor subunit alpha-2, IL-13R subunit alpha-2, and IL-13RA2. The IL13RA2 is often overexpressed in brain tumors, making Il13ra2 one of the vaccine targets for immunotherapy of glioma. IL13RA2/IL-13RA2 is a cancer-associated receptor that is present in greater than 80% of High Grade Astrocytomas (HGA) and has recently been recognized as a cytokine that predisposes breast cancer cells to metastasize. Expression of IL13Rα2 was rapidly lost from the surface of transduced cells grown in culture. The loss appeared to be related to ligands present in fetal bovine serum in the medium. None of the malignant glioma cell lines cultivated in vitro and tested to date exhibited the IL13Rα2 receptor. A recombinant virus (R5111) enters cells via its interaction with the IL13Rα2 receptor in a manner that cannot be differentiated from the interaction of wild-type virus with its receptors.
