Anti-STAT1 pS727 antibodies, human

Anti-STAT1 pS727 antibodies, human

Clone: REA525 | Dilution: 1:11
Clone REA525 recognizes the signal transducer and activator of transcription 1 (STAT1) antigen phosphorylated at serine 727 (pS727). STAT1 expression is found ubiquitously. It is involved in upregulating genes due to a signal by either type I, type II, or type III interferons. STAT1 is an essential transcription factor for macrophage activation by IFN-γ and requires phosphorylation of the C-terminal pS727 for transcriptional activity. It forms homodimers or heterodimers with STAT3 that bind to the IFN-γ activated sequence promoter element. In response to either IFN-α or IFN-β stimulation, STAT1 forms a heterodimer with STAT2 that can bind the interferon stimulated response promoter element. In either case, binding of the promoter element leads to an increased expression of interferon stimulated genes.
Additional information: Clone REA525 displays negligible binding to Fc receptors.
