Specifications for CD213α2 (IL-13Rα2) Antibody, anti-human, REAfinity™


Clone REA308 recognizes the human CD213α2 antigen, a single-pass type I membrane protein which is also known as interleukin-13 receptor subunit α-2 (IL-13Rα2). CD213α2 is a high affinity receptor for IL-13 that is used only by IL-13 and is quite distinct from CD213α1 (IL-13Rα1) that IL-13 shares with IL-4. CD213α2 is expressed by fibroblasts, smooth muscle cells, keratinocytes, and activated B cells. It has been thought to be a decoy receptor due to its short cytoplasmic tail and it exists on the cell membrane, intracellularly, and in soluble form. Recent reports revealed that membrane CD213α2 may have some signaling capabilities, and soluble CD213α2 is a critical endogenous modulator for IL-13 responses. Additionally, IL-13 signaling via CD213α2 plays a role in tumor immune surveillance.
Additional information: Clone REA308 displays negligible binding to Fc receptors.
