Temporal models suggest that the first event in IL22 receptor formation is binding of Interleukin-22 (IL22) to IL22RA1), which pre associates with JAK1 (Li et al. 2004, Jones et al. 2008, Xie et al. 2000, Xu et al. 2001).
The Interleukin-22 receptor consists of IL22RA1 and Interleukin-10 receptor subunit beta (IL10RB), which is also a component of the receptors for Interleukin-10 (IL10), Interleukin-22 (IL22), Interleukin-26 (IL26), Interleukin-28 (IL28), and Interferon lambda-1 (IFNL1).
