CC -!- FUNCTION: Transcription factor that binds to the interleukin-6 CC (IL-6)-responsive elements identified in the promoters of various CC acute-phase protein genes. CC -!- PATHWAY: Involved in the gp130-mediated signaling pathway. CC -!- SUBUNIT: Forms a homodimer or a heterodimer with a related family CC member (at least STAT1). CC -!- SUBCELLULAR LOCATION: Nuclear; translocated into the nucleus in CC response to phosphorylation. CC -!- TISSUE SPECIFICITY: Heart, brain, placenta, lung, liver, skeletal CC muscle, kidney and pancreas. CC -!- PTM: TYROSINE PHOSPHORYLATED IN RESPONSE TO IL-6, IL-11, CNTF, CC LIF, CSF-1, EGF, PDGF, IFN-ALPHA AND OSM. SERINE PHOSPHORYLATION CC IS IMPORTANT FOR THE FORMATION OF STABLE DNA-BINDING STAT3 CC HOMODIMERS AND MAXIMAL TRANSCRIPTIONAL ACTIVITY. CC -!- SIMILARITY: Belongs to the STAT family of transcription factors. CC -!- SIMILARITY: Contains 1 SH2 domain.
