Abstract:

Human MRG15 is a transcription factor that plays an important role in embryonic development, cell proliferation and senescence. The MRG15 chromo domain can interact with methylated Lys36 of histone H3. In this study, the assignment of amino acids of MRG15 chromo domain was done using solution NMR spectroscopy. The interaction between MRG15 chromo domain and H3K36me3 peptide was studied by the chemical shift perturbation approach. The binding sites (i.e., H21,Y46,W49 and W53) and dissociation constants (~1 mmol/L) were determined. These results provide give insight on the interaction between MRG15 chromo domain and histone H3 at molecular level.
