Myc and PAF1 (IMAGE) University of Würzburg Caption The red dots in the right picture show where Myc and PAF1 bind to each other. This happens mainly in the cell nuclei (dyed blue). No specific interaction is visible in reference nuclei without PAF1 (centre) or Myc (left). By the way, the absence of Myc and its growth-promoting effect significantly reduces the average size of nuclei (and entire cells).
