Background Information
Signal transducer and activator of transcription 3 (acute-phase response factor) (STAT3, synonyms: APRF, FLJ20882, MGC16063) is a member of the STAT protein family. Phosphorylated STAT3 dimerizes and translocates to the nucleus, where it regulates the transcription of target genes through binding to specific DNA-responsive elements. In addition to activation by Tyr705 phosphorylation, STAT3 also requires phosphorylation on Ser727 to achieve maximal transcriptional activity. (PMID: 21617181)
