    Protocol

    Specificity / Sensitivity

    Stat1 (D4Y6Z) Rabbit mAb recognizes endogenous levels of total Stat1 protein.

    Species Reactivity:

    Human, Mouse, Rat

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with recombinant protein specific to a region near the carboxy terminus of human Stat1 protein.

    Background

    The Stat1 transcription factor is activated in response to a large number of ligands (1) and is essential for responsiveness to IFN-α and IFN-γ (2,3). Phosphorylation of Stat1 at Tyr701 induces Stat1 dimerization, nuclear translocation, and DNA binding (4). Stat1 protein exists as a pair of isoforms, Stat1α (91 kDa) and the splice variant Stat1β (84 kDa). In most cells, both isoforms are activated by IFN-α, but only Stat1α is activated by IFN-γ. The inappropriate activation of Stat1 occurs in many tumors (5). In addition to tyrosine phosphorylation, Stat1 is also phosphorylated at Ser727 through a p38 mitogen-activated protein kinase (MAPK)-dependent pathway in response to IFN-α and other cellular stresses (6). Serine phosphorylation may be required for the maximal induction of Stat1-mediated gene activation.
