Enables interleukin-17 receptor activity and signaling receptor binding activity. Involved in several processes, including granulocyte chemotaxis; interleukin-17-mediated signaling pathway; and positive regulation of cytokine production involved in inflammatory response. Acts upstream of or within positive regulation of interleukin-13 production and positive regulation of interleukin-5 production. Located in plasma membrane. Is expressed in thymus primordium. Human ortholog(s) of this gene implicated in immunodeficiency 51. Orthologous to human IL17RA (interleukin 17 receptor A). [provided by Alliance of Genome Resources, Apr 2022]
