WebMay 9, 2024 · Activated phosphorylated STAT1 (pSTAT1) typically dimerizes with pSTAT2 to form the ISGF3 complex together with the interferon regulatory factor 9 (IRF9) ( Smith et al., 2005 ). This complex binds at the genomic level to the ISRE sequences to control a long list of interferon-induced genes ( Friedman and Stark, 1985 ). WebSTAT1 has a key role in many gene expressions that cause survival of the cell, viability or pathogen response. There are two possible transcripts (due to alternative splicing) that encode 2 isoforms of STAT1. [7] [8] STAT1α, the full-length version of the protein, is the main active isoform, responsible for most of the known functions of STAT1.
