IL-13 is a key mediator in the pathogenesis of allergic inflammation. Its receptor is comprised of IL-4Rα and IL-13Rα1, which transduct the signaling to the downstream STAT6 pathway. IL-13Rα2, also known as IL-13Ra2 and IL-13BP, serves as a decoy receptor to attenuate IL-13-induced response. IL-13Rα2 binds IL-13 with 100-300 folds higher affinity than does IL-13Rα1, but IL-13Rα2 lacks signaling motifs on its cytoplasmic tail. Mice deficient in IL-13Rα2 showed increased IgE level and IFNγ production, consistent with a phenotype of enhanced IL-13 effects. Airway hyperresponsiveness and inflammation was enhanced in IL-13Rα2 transgene mice, indicating that IL-13Rα2 blocks IL-13 mediated response. In mice, there are two discrete transcripts generated by alternative splicing, producing membrane-bound and secreted forms, respectively. Some evidences indicated that MMP-8 contributes to soluble forms of IL-13Rα2 by cleaving membrane-bound IL-13Rα2. In human, only membrane-bound transcript was found and soluble forms were absent in human plasma.

Related FAQs
- Do you guarantee that your antibodies are totally pathogen free?
-
BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.
- Does BioLegend test each Ultra-LEAF™ antibody by functional assay?
-
No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.
- Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?
-
No, BioLegend does not test for pathogens in-house unless otherwise indicated. However, we can recommend an outside vendor to perform this testing as needed.
- Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?
-
We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
