Function
(From Uniprot)
Associates with OSMR to form the interleukin-31 receptor which activates STAT3 and to a lower extent STAT1 and STAT5. May function in skin immunity. Mediates IL31-induced itch, probably in a manner dependent on cation channels TRPA1 and TRPV1. Positively regulates numbers and cycling status of immature subsets of myeloid progenitor cells in bone marrow in vivo and enhances myeloid progenitor cell survival in vitro.

- The first demonstration of the involvement of the IL-31/IL-31R axis in cancer came from studies in patients with mycosis fungoides/Sezary syndrome, the most frequent, cutaneous T cell lymphoma. Tumor cells were shown to produce IL-31, whose serum levels correlated with pruritus intensity. PMID: 28408397
