This gene encodes a member of the class II cytokine receptor family. The encoded soluble protein specifically binds to and inhibits interleukin 22 activity by blocking the interaction of interleukin 22 with its cell surface receptor. The encoded protein may be important in the regulation of inflammatory response, and has been implicated in the regulation of tumorigenesis in the colon. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2013]
Forensic Context
A study in mice demonstrated that the IL22RA2 was significantly upregulated in lung tissue following paraquat-induced epithelial-mesenchymal transition, as identified through high-throughput transcriptome sequencing and integrated ceRNA network analysis [Ma et al. DOI:10.1002/Jbt.23681].
