| Function | Component of the receptor for IL20, IL22 and IL24. Component of IL22 receptor formed by IL22RA1 and IL10RB enabling IL22 signaling via JAK/STAT pathways. IL22 also induces activation of MAPK1/MAPK3 and Akt kinases pathways. Component of one of the receptor for IL20 and IL24 formed by IL22RA1 and IL20RB also signaling through STATs activation. Mediates IL24 antiangiogenic activity as well as IL24 inhibitory effect on endothelial cell tube formation and differentiation. {ECO:0000269|PubMed:11035029, ECO:0000269|PubMed:11564763, ECO:0000269|PubMed:11706020, ECO:0000269|PubMed:12351624, ECO:0000269|PubMed:12941841, ECO:0000269|PubMed:17204547}. |
| Subcellular Location | Membrane; Single-pass type I membrane protein. |
| Tissue Specificity | Expressed in colon, liver, lung, pancreas and kidney. No expression in immune cells such as monocytes, T-cells, and NK-cells. Expressed in keratinocytes of normal skin as well as in psoriatic skin lesion. Detected in normal blood brain barrier endothelial cells as well as in multiple sclerosis lesions; Strongly expressed on central nervous system vessels within infiltrated multiple sclerosis lesions. Overexpressed in synovial fluid cells from rheumatoid arthritis and spondyloarthropathy patients. {ECO:0000269|PubMed:12407026, ECO:0000269|PubMed:15308104, ECO:0000269|PubMed:17828272, ECO:0000269|PubMed:17900301, ECO:0000269|PubMed:18061474}. |
