This entry represents the N-terminal domain in IL17RA and IL17RB in animals. This domain contains a fibronectin type-III fold. The first two fibronectin type-III domains are linked and together they bind two molecules of IL17 at one of its receptor-binding interfaces. This allows the other interface to bind to another receptor, thus allowing the IL17 family of homodimeric cytokines to coordinate two different receptors [1].	Domain
