The function of Ensembl gene identifier ENSG00000123496 (IL13RA2, interleukin 13 receptor subunit alpha 2) is as follows. Cell surface receptor that plays a role in the regulation of IL-13-mediated responses (PubMed:11861389, PubMed:17030238). Functions as a decoy receptor that inhibits IL-13- and IL-4-mediated signal transduction via the JAK-STAT pathway and thereby modulates immune responses and inflammation (PubMed:11861389, PubMed:17030238). Serves as a functional signaling receptor for IL-13 in an alternative pathway involving AP-1 ultimately leading to the production of TGFB1 (PubMed:16327802). {ECO:0000269|PubMed:11861389, ECO:0000269|PubMed:16327802, ECO:0000269|PubMed:17030238, ECO:0000269|PubMed:20223216}.
