Target description

Signal transducer and activator of transcription 1-alpha/beta (UniProt: P42224; also known as Transcription factor ISGF-3 components p91/p84, STAT1) is encoded by the STAT1 gene (Gene ID: 6772) in human. STATs (signal transducers and activators of transcription) are a family of cytoplasmic latent transcription factors that are activated to regulate gene expression in response to a large number of extracellular signaling proteins. STAT1 is activated by many different ligands including interferons, interleukins, and growth factors. STAT1 exists in two forms, the 91 kDa STAT1alpha and the 84 kDa STAT1beta, which are encoded by the same gene with splicing variant. Following ligand binding to cell surface receptors, signaling via protein kinases leads to activation of Jak kinases and tyrosine phosphorylation of STAT1 and STAT2. The phosphorylated STATs dimerize and enter the nucleus. Phosphorylation on serine 727 by several kinases including MAPK14, ERK1/2 and CAMKII following on IFN-gamma stimulation, regulates STAT1 transcriptional activity. This phosphorylation also promotes sumoylation though increasing interaction with PIAS. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
