Description

Mouse Monoclonal Antibody

This antibody reacts specifically with the tyrosine-701 phosphorylated form of STAT1 and does not exhibit appreciable cross-reactivity with corresponding tyrosine phosphorylated forms of other STAT proteins or with other endogenous phosphotyrosine-containing proteins. To confirm the exclusive recognition of tyrosine phosphorylated STAT1, Western blots were carried out on lysates of 293 cells transfected with a STAT1 expression vector together with a wild type or kinase 'dead' JAK1 expression vector. In addition, recognition of endogenous tyrosine phosphorylated STAT1 was confirmed on Western blots with cell lysates derived from serum starved or EGF-stimulated A431 cells and on Western blots with IFNa-stimulated mouse embryo fibroblast lysates.

STAT1 (signal transducers and activators of transcription 1) is a member of the STAT family of transcription factors. STAT1 can be activated by interferon-alpha, interferon-gamma, EGF, PDGF and IL6. STAT1 is known to regulate several genes which are involved in cell growth, apoptosis, immune responses, and lipid metabolism. Further, STAT1 plays an important role in mediating cell viability in response to different cell stimuli and pathogen exposure. The STAT1 gene is located on chromosome 2. STAT1 is activated to regulate gene expression in response to extracellular signaling polypeptides including cytokines, interferons, and growth factors. After phosphorylation by JAK tyrosine kinases, STAT1 enters the nucleus to regulate transcription of many different genes. Among the seven STATs types, STAT1, STAT3, STAT5a, and STAT5b have a wide activation profile. STAT1 is activated by many different ligands including IFN family (IFN-Alpha, IFN-Beta, IFN-gamma and IL-10), gp130 family (IL-6, IL-11, LIF, CNTF, and G-CSF), and receptor tyrosine kinases (EGF, PDGF, and CSF-1). Two alternatively spliced transcript variants encoding distinct isoforms of STAT1 have been described.
