Inactivation of nuclear STAT1 occurs rapidly following binding to chromatin and activation of target gene transcription.
Subsequently STAT1 is dephosphorylated by phosphatases such as PTPN2 (TCP45) and PTPN11 (SHP2), and dephosphorylated STAT1
returns to cytoplasm, where it can potentially serve as the substrate for subsequent rounds of activation and inactivation.

Probably, acetylation of STAT1 on lysine residues 410 and 413 in the nucleus results in enhanced interaction with TCP45 (PTPN2) and increased dephosphorylation
