WebInterferons (IFNs) activate the first lines of defense against viruses, and promote innate and adaptive immune responses to viruses. We report that the immediate early 1 (IE1) protein of human cytomegalovirus (HCMV) disrupts signaling by IFNγ. The carboxyl-terminal region of IE1 is required for this function. We found no defect in the initial events in IFNγ signaling … cGAS is a 522 amino acid protein and a member of the nucleotidyltransferase family. N-terminal residues 1-212 are necessary to bind dsDNA. This region may contain two different DNA binding domains. C-terminal residues 213-522 contain part of the nucleotidyltransferase (NTase) motif and a Mab21 domain and are highly conserved in cGAS from zebrafish to humans. These regions are necessary to form the catalytic pocket for the cGAS substrates: GTP and ATP, and to perfor… WebMay 1, 2005 · The CRKL–STAT5 complex translocates to the nucleus and binds specific GAS (IFN-γ-activated site) elements that are present in the promoters of certain IFN … iam worldwide pure organic barley

WebIFN-γ is the prototypic ‘macrophage-activating factor’ that augments cytokine and chemokine production, phagocytosis and intracellular killing of microbial pathogens. IFN-γ also promotes innate immunity by increasing ILC1 function. WebThe first STAT proteins were identified as the regulatory cytoplasmic components of the IFN-γ-induced transcription factor complex, interferon-stimulated response element-3 (ISGF3). Two splice variants of STAT1, STAT2 and the DNA-binding subunit p48, were found to bind the ISRE enhancer as a multiprotein complex in response to IFN-γ.

http://www.ftgas.net/ WebOct 7, 2005 · AAF is a homodimer of Stat1, whereas ISGF3 is a heterotrimeric complex of Stat1, Stat2 and IRF-9 (also known as p48 or ISGF3γ). AAF and ISGF3 translocate into the nucleus, and bind to specific DNA sequences, named the IFN-γ-activated sequence (GAS) and the IFN-stimulated response element (ISRE), respectively.
