    TbTFIIS2-1, one of the two TFIIS homologues of Trypanosome brucei (T. brucei), cooperates with TbTFIIS1 in regulating transcription in T. brcuei. Structurally divergent from other TFIIS homologues from higher organisms, TbTFIIS2-1 contains an additional N-terminal PWWP domain besides other three conserved domains, which may imply potential role of TbTFIIS2-1 in transcription regulation. Here, we determined the solution structure of PWWP domain of TbTFIIS2-1 by NMR spectroscopy, which was the first solution structure of PWWP domain solved in trypanosomatid. In spite of poor sequence similarity between PWWP domains, this domain of TbTFIIS2-1 adopts a conserved 3D-structure, which contains a five-stranded β-barrel and a C-terminal α-helix. Furthermore, we found that TbTFIIS2-1 PWWP domain may be a protein-protein interaction module without the ability of DNA recognition and methyl-group interaction.
