Associates with IL31RA to form the IL31 receptor. Binds IL31 to activate STAT3 and possibly STAT1 and STAT5. Capable of transducing OSM-specific signaling events.
Here we identify a four-helix bundle cytokine we have called interleukin 31 (il-31), which is preferentially produced by t helper type 2 cells. Il-31 signals through a receptor composed of il-31 receptor a and oncostatin m receptor.
