Description

General description

Signal transducer and activator of transcription 3 (UniProt P40763; also known as Acute-phase response factor, DNA-binding protein APRF) is encoded by the STAT3 (also known as ADMIO, APRF, HIES) gene (Gene ID 6774) in human. STAT proteins are latent cytoplasmic transcription factors that have the dual function of signal transduction and activation of transcription. STATs are activated by tyrosine phosphorylation in response to different ligands, after which they translocate to the cell nucleus. The N-terminal region is highly homologous among the STAT proteins and surrounds a completely conserved arginine residue. STATs are a part of the JAK-STAT signaling pathway – a major pathway of the immune system. All cytokines transduce critical signals through this pathway. STAT3 is known to be activated by IFN alpha but not IFN beta. The transcription factors associated with STAT3 are cJun and cyclic AMP responsive enhancer binding protein (CREB). STAT3 gene knockout in mice is lethal at the early embryonic stage.

~88 kDa observed. Uncharacterized band(s) may appear in some lysates.

Immunogen

Epitope: STAT3 K180me3

KLH-conjugated linear peptide corresponding to the STAT3 K180me3 of human trimethyl STAT3 (Lys180)

Application

Immunoprecipitation Analysis: 5.0 µg from a representative lot immunoprecipitated STAT3 trimethylated on Lys180 in 0.5 mg of mouse embryonic stem cell lysate.
Peptide Inhibition Assay: Target specificity of a representative lot was confirmed by immunogen peptide blocking prior to Western blotting analysis (0.5 µg/mL) ) of mouse embryonic stem cell lysate (10 µg/lane) . Only the immunogen peptide, but not the corresponding peptide without the Lys180 trimethylation modification, blocked the detection of the target band.
