IL-22R alpha 1 Protein, Rat (HEK293, His)

IL-22R alpha 1 (IL22RA1) Protein is an IL-22 receptor. IL-22R alpha 1 Protein interacts with IL-22 to activate the JAK/STAT cascade thereby inhibits IL-22 mediated promotion of cell proliferation and anti-apoptosis. IL-22R alpha 1 Protein, Rat (HEK293, His) is expressed by HEK 293 cells, with a His tag at the C-terminus^[1].

IL-22R alpha 1 (IL22RA1) Protein is a single-pass type I membrane protein. IL-22R alpha 1 expresses in colon, liver, lung, pancreas and kidney. IL-22R alpha 1 is primarily present on epithelial cells and certain monocyte subsets, and very limited IL-22R alpha 1 expression is found on other immune cells^[1][2].
The sequence of amino acids in IL-22R alpha 1 from different species is very different (less than 85% similarity among human, rat and Canine).
IL-22R alpha 1 is an essential component of the high-affinity IL-22 receptor enabling IL-22 signaling via JAK/STAT pathways. IL-22R alpha 1 is a component of one of the receptors for IL-20 and IL-24 formed and signaling through STATs activation. IL-22R alpha 1 mediates IL-24 antiangiogenic activity as well as IL24 inhibitory effect on endothelial cell tube formation and differentiation^[2][3].

Rat IL-22R alpha 1, His Tag immobilized on CM5 Chip can bind Biotinylated Mouse IL-22, His Tag with an affinity constant of 0.145 μM as determined in SPR assay (Biacore T200).
