STAT3 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 STAT3 induces nuclear translocation to activate transcription. STAT3 forms both homo- and heterotrimers and is involved in the activation of genes required for cell growth and apoptosis. STAT3 is also involved in gp130 signaling and binds to IL-6 response elements in various acute phase protein promoters. STAT3 is phosphorylated by signaling from IFNs, EGF, FGF, IL-5, HGF, LIF, and BMP2. STAT3 activity is inhibited by PIAS3 and GRIM-19 and can also be regulated by Rac1 protein.

Antigen Details

770 amino acids with a predicted molecular weight of 88.1 kD. Contains a C-terminal SH2 domain responsible for homo- or heterodimerization.

Phosphorylated in response to cytokine signaling by receptor-associated kinases; translocates to nucleus to act as transcriptional activator. Activates a wide variety of genes involved in cell growth and apoptosis, involved in gp130-related signaling.

STAT3 forms a homodimer or a heterodimer with other STAT family members. Interacts with IL31RA, NCOA1, PELP1, SIPAR, SOCS7, STATIP1, CAV2, DAPK3, EIF2AK2, PIAS3, and TMF1.
