UniProtKB - Q969J5 (I22R2_HUMAN)
Protein
Interleukin-22 receptor subunit alpha-2
Gene
IL22RA2
Organism
Homo sapiens (Human)
Status
Functioni
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.
Isoform 1 may play a role in establishing and maintaining successful pregnancy.
