This antibody is designed, produced, and validated as part of a collaboration between Rockland and the National Cancer Institute (NCI) and is suitable for Cancer, Immunology and Nuclear Signaling research. Signal transducer and activator of transcription 1 (Stat1) belongs to a family of cytoplasmic transcription factors that can be activated (phosphorylated) by a cell surface receptor. Phosphorylation of Stat1 at Tyr701 induces Stat1 dimerization, nuclear translocation and DNA binding. Stat1 has two isoforms, Stat1a (91 kDa) and the splice variant Stat1b (84 kDa). Stat1 has been found to be inappropriately activated in many tumors. In addition to tyrosine phosphorylation, Stat1 is phosphorylated through a p38 mitogen-activated protein kinase (MAPK)-dependent pathway at Ser727 in response to IFN-g and other cellular stresses. Stat1 is localized in the cytoplasm and upon phosphorylation at Y701 is translocated to the nucleus.
