The STAT (Signal Transducer and Activator of Transcription) proteins represent a family of transcription factors that function as downstream effectors of growth factor and cytokine signaling cascades. STAT3 plays a central role in cell cycle progression, inhibition of apoptosis, and transformation. Phosphorylation of STAT3 at tyrosine 705 by JAK and receptor tyrosine kinases has been shown to increase STAT3 activation through multiple mechanisms, including increased homodimerization and concomitant translocation to the nucleus, as well as through increasing STAT3 affinity for response elements found in the regulatory promoters of its target genes. High levels of STAT3 activation have been described in several cancers and are of considerable interest for therapeutic intervention.Product Details
