- STAT3 is a 770 amino acid protein of 88 kD. It consists of a DNA binding domain, a SH2 domain, a regulatory tyrosine responsible for binding of SH2 domain, and a C-terminal transactivation domain.
- STAT3 is tyrosine phosphorylated by receptor kinases in response to a variety of cytokines and growth factors. It forms homo- or heterodimer with STAT1 when tyrosine is phosphorylated, and then translocates to nucleus, acting as a transcription regulator. It is also essential for the differentiation of TH17 cells, which is involved in autoimmune diseases.
