This gene encodes a membrane protein belonging to the interleukin-17 receptor (IL-17R) protein family. The encoded protein is a component of the interleukin-17 receptor signaling complex, and the interaction between this protein and IL-17R does not require the interleukin (PMID: 19079364). The gene product also affects fibroblast growth factor signaling, inhibiting or stimulating growth through MAPK/ERK signaling (PMID: 21663947, 18096367). [provided by RefSeq, Nov 2011]
