STAT1 and infection: Three days after infection, the largest increase was observed in phosphosites of the interferon-induced IFIH1 (S301-p) and STAT1 (S727-p), the transcription factor SP (ENSP00000375902.3 S378-p and S244-p), and a protein involved in trafficking of amino acids - CLTRN (S177-p) (two-sided t test, p < 0.05, 5% FDR, Figure S15a, Supplementary Dataset 11b), whereas only the heat shock protein HSP90AB1 (ENSP00000325875.3 S226-p) had an increase 7 days after infection (two-sided t test, p < 0.05, 5% FDR, Figure S15b, Supplementary Dataset 11c).
