背景（Background）
Oncostatin-M-specific receptor subunit beta(OSMRB) alos know as Interleukin-31 receptor subunit beta (IL-31RB), is an alternative subunit (OSMRβ) for an OSM receptor complex (a heterodimer of gp130 and OSMRβ), that is activated by OSM but not by LIF. OSMR beta associates with the low affinity OSM·gp130 complex to form a high affinity heterodimeric receptor that is capable of transducing OSM-specific signaling events.
