Biolegend, 666410, Alexa Fluor® 647 anti-STAT1 Phospho (Tyr701) Antibody, 100tests

STAT1, also known as signal transduction and activator of transcription 1, is a ubiquitously expressed cytoplasmic protein and is activated in response to cytokine signaling, including IFN-α, IFN-γ, EGF, PDGF, and IL-6. Upon activation, STAT1 is phosphorylated at Tyrosine 701 (Tyr701) by receptor-associated kinases, including JAK1, JAK2, and TYK2. This results in STAT1 dimerization and subsequent translocation to the nucleus, where it functions as a transcriptional activator. STAT1 is involved in IFN-mediated immune responses, and STAT1-deficient mice are highly sensitive to bacterial and viral infections.
