Study reports 2.53 A atomic structures of both the human PAF1/CTR9 and yeast Paf1/Ctr9 heterodimers. Results clearly reveal that the heterodimer of PAF1/CTR9 or Paf1/Ctr9 is the core component of evolutionarily conserved multifunctional polymerase-associated factor 1 complex (Paf1C) and is important for human PAF1C or yeast Paf1C assembly, yeast viability, and Paf1C-mediated histone modifications.
