STAT is a family of cytoplasmic protein that regulates many aspects of growth, survival and differentiation in cells. The Janus kinase family of transcription factors is activated, and dysregulation of this pathway, which promotes angiogenesis, tumor survival, and immunosuppression, is frequently seen in primary tumors. Gene knockout studies have shown that STAT proteins are important for immune system development and operation, immune tolerance maintenance, and tumor surveillance.Initially, STAT proteins were thought to be dormant cytoplasmic transcription factors that needed to be phosphorylated in order to be retained in the nucleus. While awaiting an activation signal, the unphosphorylated STAT proteins move back and forth between the cytosol and the nucleus. The transcription of cytokine-inducible genes is activated once the activated transcription factor enters the nucleus and binds to the consensus DNA-recognition motif known as gamma-activated sites (GAS) in the promoter region.
