STAT6 (phospho Tyr641)
Background
STAT6 Tyr641 is conserved JAK-catalyzed tyrosine-activation site and specific biomarker for STAT6-pathway activation. Upon IL-4 / IL-13 receptor ligation, activated JAK phosphorylates STAT6 at Tyr641. Phosphorylated STAT6 undergoes homodimerization and nuclear translocation, binding target-gene promoters to drive transcription governing Th2-cell differentiation, M2-macrophage polarization, IgE class-switching and allergic inflammation. Tyr641 phosphorylation is prerequisite for STAT6 nuclear import and transcriptional competence.
