-[[http://www.uniprot.org/uniprot/I17RA_HUMAN I17RA_HUMAN]] Defects in IL17RA are the cause of familial candidiasis type 5 (CANDF5) [MIM:[http://omim.org/entry/613953 613953]]. CANDF5 is a rare disorder with altered immune responses and impaired clearance of fungal infections, selective against Candida. It is characterized by persistent and/or recurrent infections of the skin, nails and mucous membranes caused by organisms of the genus Candida, mainly Candida albicans.<ref>PMID:21350122</ref>

+== Publication Abstract from PubMed ==
+The constituent polypeptides of the interleukin-17 family form six different homodimeric cytokines (IL-17A-F) and the heterodimeric IL-17A/F. Their interactions with IL-17 receptors A-E (IL-17RA-E) mediate host defenses while also contributing to inflammatory and autoimmune responses. IL-17A and IL-17F both preferentially engage a receptor complex containing one molecule of IL-17RA and one molecule of IL-17RC. More generally, IL-17RA appears to be a shared receptor that pairs with other members of its family to allow signaling of different IL-17 cytokines. Here we report crystal structures of homodimeric IL-17A and its complex with IL-17RA. Binding to IL-17RA at one side of the IL-17A molecule induces a conformational change in the second, symmetry-related receptor site of IL-17A. This change favors, and is sufficient to account for, the selection of a different receptor polypeptide to complete the cytokine-receptor complex. The structural results are supported by biophysical studies with IL-17A variants produced by site-directed mutagenesis.
