General description

A cell-permeable STAT3 SH2 domain-derived (588-615) 28-mer peptide that competitively prevents STAT3 binding to cognate pTyr peptide motif, represses STAT3 dimerization, induces apoptosis and acts as a selective constitutive STAT3 activation inhibitor in several tumor cells at 50 µM. Shown to localize in nucleus, potently block STAT3 phosphorylation, DNA-binding and transcriptional activities with minimal effect on STAT1, STAT5 and MEK signaling.
The STAT3 Inhibitor XII, SPI controls the biological activity of STAT3. This small molecule/inhibitor is primarily used for Phosphorylation & Dephosphorylation applications.

JAK/STAT Signaling Research Focus

The Janus kinase (JAK)/signal transducers and activators of transcription (STAT) signaling pathway plays an important role in cell proliferation, cell differentiation, cell migration, and cell death. It is the principal signaling mechanism for a variety of cytokines and growth factors. Constitutive activation or dysregulation of JAK/STAT signaling can result in inflammatory disease, erythrocytosis, gigantism, and leukemia.
