human STAT3, around phosphorylation site of Tyr705, aa 672-721
Background
STAT3 Tyr705 is the major JAK-catalysed tyrosine-phosphorylation site and canonical activation marker of STAT3. Upon stimulation by interleukins, growth factors or cytokines, JAK-mediated Tyr705 phosphorylation triggers STAT3 homodimerization, nuclear translocation and target-gene binding to drive transcription of genes governing proliferation, anti-apoptosis, EMT, inflammation and stem-cell features. Tyr705 phosphorylation is prerequisite for STAT3 nuclear import and transcriptional activity. Constitutive Tyr705 phosphorylation represents a common oncogenic driver across multiple malignancies.
