In other organisms, this gene is better known as transcription elongation factor II S (TFIIS). It mainly helps to resolve backtracked elongation complexes by inducing a cut in the RNAP active site, so reaction becomes possible again. It is also found in the eukaryotic transcription preinitiation complex.^[8] A homolog in archaea performs the same main task, while bacteria use the non-homologous Gre.^[9]
