Human IL13RA2 mRNA encodes the human interleukin 13 receptor subunit alpha 2 (IL13RA2) protein, a subuint of the interleukin 13 receptor complex. IL13RA2 binds IL13 with high affinity, but lacks cytoplasmic domain, and does not appear to function as a signal mediator. It is reported to play a role in the internalization of IL13.
