Specificity
This antibody recognises signal transducer and activator of transcription 1-alpha/beta (STAT1) also known as transcription factor ISGF-3 components p91/p84, when phosphorylated at serine 727. STAT1 is part of the transcription factor STAT family of proteins. STAT proteins form homo- or hetero-dimers once phosphorylated by receptor associated kinases. Following dimerization STAT proteins then translocate to the cell nucleus. Phosphorylation of STAT1 at serine 727 occurs via p38 MAPK (MAPK14) pathways.
