Figure 4. Mmi1 drives Rrp6-dependent heterochromatin gene silencing at pericentromeric regions. (A) Upper part, TNAAAC-rich sequence present in nam5, 6 and 7 lncRNAs. Lower part, schematic representation of S. pombe three centromeres showing the different pericentromeric DNA repeats susceptible to produce nam5, 6 and 7 (green arrows).
