Strawberry Notch Homolog 2 (SBNO2)

IL-10 regulates anti-inflammatory signaling via the activation of STAT3, which in turn controls the induction of a gene expression program whose products execute inhibitory effects on proinflammatory mediator production. IL-10 induces the expression of an ETS family transcriptional repressor, ETV3, and a helicase family corepressor, Strawberry notch homologue 2 (SBNO2), in mouse and human macrophages. IL-10-mediated induction of ETV3 and SBNO2 expression was dependent upon both STAT3 and a stimulus through the TLR pathway.  ETV3 and SBNO2 repressed NF-kappaB- but not IFN regulatory factor 7 (IRF7)-activated transcriptional reporters. ETV3 and SBNO2 are components of the pathways that contribute to the downstream anti-inflammatory effects of IL-10.
