Add to Cart


Binding Site: Ser727 WB Dilution: 500~1000

IHC Dilution: 50~100 Function: Transcription factor that binds to the interleukin-6 (IL-6)-responsive elements identified in the promoters of various acute-phase protein genes. Activated by IL31 through IL31RA.

Subunit: Forms a homodimer or a heterodimer with a related family member (at least STAT1). Interacts with NCOA1, PELP1, SOCS7 and STATIP1. Interacts with HCV core protein. Interacts with IL23R in presence of IL23. Interacts with IL31RA.

Subcellular Location: Cytoplasm. Nucleus. Note=Translocated into the nucleus in response to phosphorylation.

Tissue Specificity: Heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas.

Ptm: Tyrosine phosphorylated in response to IL-6, IL-11, CNTF, LIF, CSF-1, EGF, PDGF, IFN-alpha and OSM. Phosphorylated on serine upon DNA damage, probably by ATM or ATR. Serine phosphorylation is important for the formation of stable DNA-binding STAT3 homodimers and maximal transcriptional activity.

Miscellaneous: Involved in the gp130-mediated signaling pathway.

Similarity: Belongs to the transcription factor STAT family.

Similarity: Contains 1 SH2 domain. [1] Akira S., Nishio Y., Inoue M., Wang X.-J., Wei S., Matsusaka T., Yoshida K., Sudo T., Naruto M., Kishimoto T., et al.
