IL-17RC

IL-17RC (Interleukin 17 receptor C), a receptor for IL-17A and IL-17F, is a type I membrane glycoprotein. It is expressed on a variety of nonhematopoietic cell types, and plays a role in inflammatory diseases, including autoimmunity and certain cancers. IL-17 cytokine family members IL-17A and IL-17F mediate inflammatory activities via the IL-17R complex, comprised of the IL-17RA and IL-17RC subunits. The expression profile and tissue distribution of IL-17RC suggest that the gene regulation of IL-17RC differs considerably from IL-17RA[1].
IL-17RA co-immunoprecipitates with IL-17RC in a ligand-dependent manner, raising the possibility that the ligand-dependent loss of FRET between IL-17RA subunits results from oligomerization with IL-17RC. Consistent with this, IL-17RC also forms large, multimeric complexes consistent with oligomerization with IL-17RA. IL-17RC forms heterodimers with IL-17RA to mediate IL-17A and IL-17F signals in mouse stromal cells and human gastric adenocarcinoma AGS cells and synoviocytes. Specific overexpression of IL-17RC protects prostate cancer cell lines from TNFα-induced apoptosis. IL-17RC also contributes to autoimmune disease pathogenesis[1][2].
