Interleukin 13 Receptor Alpha 2 (IL13Ra2) Antibody

Background

Interleukin-13 receptor subunit alpha-2 (IL13RA2) is a protein encoded by the IL13RA2 gene, which functions as part of the immune system’s response to inflammation and certain immune-regulatory mechanisms. IL13RA2 is closely related to interleukin-13 receptor subunit alpha-1 (IL13RA1), both of which bind to the cytokine interleukin-13 (IL-13). However, IL13RA2 is distinctive in that it acts as a “decoy” receptor, binding IL-13 with high affinity but not actively initiating intracellular signaling, thereby modulating the effects of IL-13 on immune responses. IL13RA2 has roles in regulating allergic reactions and fibrotic processes and is often upregulated in various pathological conditions, including certain cancers. The protein's interactions with IL-13 have implications for tissue remodeling, fibrosis, and immune regulation, making it an important target in the fields of immunology, oncology, and fibrosis research.
