[https://www.uniprot.org/uniprot/I22R2_HUMAN I22R2_HUMAN] Isoform 2 is a receptor for IL22. Binds to IL22, prevents interaction with the functional IL-22R complex and blocks the activity of IL22 (in vitro). May play an important role as an IL22 antagonist in the regulation of inflammatory responses.<ref>PMID:11390454</ref> <ref>PMID:11390453</ref> <ref>PMID:11481447</ref> Isoform 1 may play a role in establishing and maintaining successful pregnancy.<ref>PMID:11390454</ref> <ref>PMID:11390453</ref> <ref>PMID:11481447</ref>

== Publication Abstract from PubMed ==
 +
Interleukin-22 (IL-22) plays an important role in the regulation of immune and inflammatory responses in mammals. The IL-22 binding protein (IL-22BP), a soluble receptor that specifically binds IL-22, prevents the IL-22/interleukin-22 receptor 1 (IL-22R1)/interleukin-10 receptor 2 (IL-10R2) complex assembly and blocks IL-22 biological activity. Here we present the crystal structure of the IL-22/IL-22BP complex at 2.75 A resolution. The structure reveals IL-22BP residues critical for IL-22 binding, which were confirmed by site-directed mutagenesis and functional studies. Comparison of IL-22/IL-22BP and IL-22/IL-22R1 crystal structures shows that both receptors display an overlapping IL-22 binding surface, which is consistent with the inhibitory role played by IL-22 binding protein.
