Antigen, CD213a1

An Interleukin Receptor subunit with specificity for Interleukin-13. It dimerizes with the Interleukin-4 Receptor alpha Subunit to form the Type II Interleukin-4 Receptor which has specificity for both Interleukin-4 and Interleukin-13. Signaling of this receptor subunit occurs through the interaction of its cytoplasmic domain with Janus Kinases such as the TYK2 Kinase.
