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 fi ve-stranded beta-barrel and a C-terminal alpha-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.
