Phospho-STAT6 Y641 in U937 Human Cell Line. STAT6 phosphorylated at Y641 was detected in immersion fixed U937 human histiocytic lymphoma cell line treated with Recombinant Human IL-4 (Catalog # 204-IL) using Rat Anti-Human Phospho-STAT6 Y641 Monoclonal Antibody (Catalog # MAB37172) at 25 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rat IgG Secondary Antibody (red; Catalog # NL013) and counterstained with DAPI (blue). Specific staining was localized to nuclei.

Background: STAT6

Signal Transducer and Activator of Transcription 6 (STAT6) mediates the signaling of cytokines such as IL-4 and IL-13. STAT6 acts as a signal transducer in the cytoplasm and, upon phosphorylation at Y641, translocates to the nucleus and binds to the DNA consensus site TTCN₄GAA. Knockout studies in mice suggest that STAT6 functions in differentiation of T helper 2 (Th2) cells, expression of cell surface markers, and class switch of immunoglobulins.
