Interleukin-13 Receptor Subunit Alpha-2 (IL13RA2) Mouse Recombinant Protein

This gene encodes a receptor protein that binds to interleukin 13 (IL-13) with very high affinity. The encoded protein acts as a decoy receptor, and does not elicit any signal upon the binding of IL-13. Mice lacking the encoded protein exhibit increased levels of serum immunoglobulins, immune-dependent production of interferon gamma and, increased bone marrow macrophage progenitor frequency. Macrophages lacking the encoded protein release less nitric oxide and IL-12 in response to lipopolysaccharide. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Apr 2015]

IL13RA2: a type I membrane protein that binds with high affinity to interleukin-13 (IL13), but not to interleukin-4 (IL4). Lacks a cytoplasmic domain, and does not appear to function as a signal mediator. It is reported to play a role in the internalization of IL13. A member of the Cancer-Testis Antigen (CTA) superfamily. CTAs may play roles in embryonal development and tumor transformation or aspects of tumor progression. CTAs were once thought to be silenced in most normal adult tissues, with limited expression in fetal, placental, testis, and ovarian cells. These proteins are now known to be aberrantly expressed in various cancers and many are capable of eliciting humoral and cellular immune responses. The WSXWS motif appears to be necessary for proper protein folding and thereby efficient intracellular transport and cell-surface receptor binding. The box 1 motif is required for JAK interaction and/or activation. Often overexpressed in brain tumors. A potential vaccine targets for immunotherapy of glioma.
