CD213A2, also known as IL13Rα2, is a type I transmembrane protein belonging to the hematopoietin receptor family. It binds interleukin-13 (IL-13) with high affinity but lacks a functional cytoplasmic signaling domain, suggesting that it primarily acts as a decoy receptor, antagonizing IL-13 signaling mediated by the IL-13Rα1/IL-4Rα complex. IL13Rα2 is expressed in fibroblasts, smooth muscle cells, keratinocytes, and activated B cells, though its surface expression is tightly regulated and much of it resides intracellularly or in soluble form. In addition to inhibiting IL-13 activity, IL13Rα2 has been reported to suppress IL-4 signaling via physical interaction with IL-4Rα, while paradoxically promoting TGF-β production and fibrosis. Importantly, IL13Rα2 is highly and specifically overexpressed in certain cancers, such as glioblastoma multiforme and high-grade astrocytomas, making it a promising target for tumor-specific immunotherapies and viral vector-mediated gene delivery approaches.
