InnateDB Annotation
STAT3 is a transcription factor that mediates interleukin-10 (IL-10) cytokine signalling.
STAT3 and SRC have a role in the immunoregulation of dendritic cells (DCs) where apoptotic cells-induced inhibition of dendritic cells (DCs) requires MerTK-dependent activation of SRC and STAT3.
STAT3 mediates mucosa-protective and anti-inflammatory functions in epithelial and myeloid cells and promotes inflammation in T cells.
STAT3 binds to multiple genes involved in Th17 cell differentiation, cell activation, proliferation, and survival, regulating both expression, epigenetic modifications, and targets the T cell function in inflammation and homeostasis.
STAT3 is an essential mediator of emergency granulopoiesis via its regulation of transcription factors CEBPA and CEBPB that direct granulocyte colony-stimulating factor (G-CSF)-responsive myeloid progenitor expansion.
STAT3 is a negative regulator of type I IFN-mediated anti-viral responses. (Demonstrated in mouse)
In alveolar epithelium, IL22 upregulates DEFB4A gene expression via STAT3.
MIR29A inhibits IL10-induced cytokine release by targeting JAK-STAT3 in monocytes during sepsis.

[Mus musculus] Stat3 is required for maximal Osm-induced lung Cxcl5 expression and subsequent neutrophil recruitment during bacterial pneumonia.
Entrez Gene
Summary The protein encoded by this gene is a member of the STAT protein family. In response to cytokines and growth factors, STAT family members are phosphorylated by the receptor associated kinases, and then form homo- or heterodimers that translocate to the cell nucleus where they act as transcription activators. This protein is activated through phosphorylation in response to various cytokines and growth factors including IFNs, EGF, IL5, IL6, HGF, LIF and BMP2. This protein mediates the expression of a variety of genes in response to cell stimuli, and thus plays a key role in many cellular processes such as cell growth and apoptosis. The small GTPase Rac1 has been shown to bind and regulate the activity of this protein. PIAS3 protein is a specific inhibitor of this protein. Three alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Jul 2008]
