|Detection of OSM R beta in D3 Mouse Cell Line by Flow Cytometry. D3 mouse embryonic stem cell line was stained with Rat Anti-Mouse OSM R beta Alexa Fluor® 700‑conjugated Monoclonal Antibody (Catalog # FAB662N, filled histogram) or isotype control antibody (Catalog # IC006N, open histogram).

Oncostatin M (OSM) is a member of the IL-6 family of cytokines that share the gp130 as a common signal transducing receptor subunit. Human OSM signals through two types of human OSM receptor complexes: the type I complex comprising the leukemia inhibitory factor receptor beta (LIF R beta ) and gp130, the type II complex made up of OSM Receptor beta (OSM R beta ) and gp130. In contrast, mouse OSM signals only through the mouse OSM R beta and gp130 complex. Mouse OSM R beta cDNA encodes a 971 amino acid (aa) type I transmembrane protein which contains a 23 aa signal peptide, an extracellular domain of 714 aa, a transmembrane domain of 20 aa and a 214 aa cytoplasmic domain. Mouse OSM R beta alone binds mOSM with low-affinity but forms a high-affinity binding complex in the presence of gp130. Mouse OSM R beta is 55% identical at the amino acid sequence level to human OSM R beta.
