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]

Interactions

TCEA1 has been shown to interact with GTF2H1[10][11] and POLR2A.[10][11][12]
