Background Information

STAT1 (signal transducers and activators of transcription 1) is a member of the STAT protein family. STAT family members are phosphorylated by the receptor associated kinases, and then form homo-or heterodimers that translocate to the cell nucleus where they act as transcription activators. The phosphorylation of STAT1 at Tyr701 promotes the dimerization of STAT1 and its translocation into the nucleus where it binds the GAS promoter to allow the transcription of inflammatory response genes(PMID: 31408005). The transcript of STAT1 undergoes alternative splicing, resulting in two isoforms: STAT1α (91 kDa) and STAT1β (84 kDa)(PMID: 20159032).
