IL22RA1Interleukin 22 receptor, alpha 1 is a protein that in humans is encoded by the IL22RA1 gene.FunctionThe protein encoded by this gene belongs to the class II cytokine receptor family, and has been shown to be a receptor for interleukin 22. IL22 receptor is a protein complex that consists of this protein and interleukin 10 receptor, beta, a subunit also shared by the receptor complex for interleukin 10. This gene and interleukin 28 receptor, alpha form a cytokine receptor gene cluster in the chromosomal region 1p36.
