Alternate Names for STAT3 Antibody (7G3H4)

  • Acute-phase response factor
  • APRFMGC16063

STAT 3 is an 88 kD member of the STAT (signal transducer and activators of transcription) protein family that is phosphorylated in response to cytokine receptor-associated kinase activity. Phosphorylation of STAT 3 induces nuclear translocation to activate transcription. STAT3 is expressed in brain, heart, placenta, lung, liver, skeletal muscle, kidney, and pancreas. STAT 3 forms both homo- and heterotrimers and is involved in the activation of genes required for cell growth and apoptosis. STAT 3 is also involved in gp130 signaling and binds to IL-6 response elements in various acute phase protein promoters. STAT 3 is phosphorylated by signaling from IFNs, EGF, FGF, IL-5, HGF, LIF, and BMP2. STAT 3 activity is inhibited by PIAS3 and GRIM-19 and can also be regulated by Rac1 protein. STAT 3 interacts with Rac1, STAT 1, and NCOA1 proteins. The Poly6246 antibody recognizes the C-terminal region of human, mouse, and rat STAT3 and has been shown to be useful for Western blotting, immunoprecipitation, and immunohistochemistry. The Poly6246 antibody does not react with STAT3b. Interacts with Rac1, associates with STAT1, NCOA1
