  • In eukaryotes, the DNA of the genome is packaged with histone proteins to form nucleosomal filaments, which are, in turn, folded into a series of less well understood chromatin structures. Post-translational modifications of histone tail domains modulate chromatin structure and gene expression. Of these, histone ubiquitination is poorly understood. Here we show that the ubiquitin-conjugating enzyme Rad6 (Ubc2) mediates methylation of histone H3 at lysine 4 (Lys 4) through ubiquitination of H2B… CONTINUE READING
