Signal transducer and activator of transcription 3 (Stat3) belongs to a family of cytoplasmic transcription factors that can be activated by phosphorylation by its cell surface receptor. Stat3 plays a key role in many cellular processes such as cell growth and apoptosis. It also mediates cellular responses to interleukins, KITLG/SCF,EGF, IFN-alpha and other growth factors and may mediate cellular responses to activated FGFR1, FGFR2, FGFR3 and FGFR4. Stat3 forms a homodimer or a heterodimer with a related family member (e.g. STAT1). Activation occurs through phosphorylation of tyrosine 705 and serine 727. Phosphorylation of Stat3 at Tyr705 induces Stat3 dimerization and nuclear translocation. Serine phosphorylation is important for stable DNA-binding of Stat3 homodimers and maximal transcriptional activity. Stat3 can have a dual role in cancer, it has been found that Stat3 protein can promote oncogenesis and have a tumor suppressor role depending upon the mutational background of the tumor.

Target Details

STAT3  - View All STAT3 Products
Conjugated Peptide
STAT3 affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with synthetic monomethylated or asymmetric dimethylated peptides surrounding Arginine 31 of human STAT.
Anti-STAT3 was affinity purified from monospecific antiserum by immunoaffinity chromatography. This antibody reacts with all STAT3 modifications. Cross-reactivity is seen against STAT1 and STAT4. BLAST analysis was used to suggest cross-reactivity with Human, mouse, and rat. Cross-reactivity with STAT3 from other sources has not been determined.

Application Details

Dot Blot
Anti-STAT3 antibody has been tested by Dot Blot and is useful for Western Blot. Specific conditions for reactivity should be optimized by the end user. Expect a band approximately ~88 kDa corresponding to STAT3 protein by Western Blotting in the appropriate cell lysate or extract.
