Fig. 7. Model of DNA-protein organisation in the PML-NBs at the G2 phase. (A) Transverse section of a PML-NB. (B) Detail of the different protein layers. The numbers indicate the following references: 1 (Paull et al., 2001; Cable et al., 2003); 2 (Zhao et al., 2000); 3 (Le Douarin et al., 1996; McDowell et al., 1999); 4 (Xue et al., 2003; Tang et al., 2004); 5 (Jang et al., 2002); 6 (Sternsdorf et al., 1997b); 7 (Eladad et al., 2005); 8 (Müller et al., 1998). The arrows for the references correspond to protein-protein or protein-DNA interactions (straight bi-headed arrows) and to protein-sumoylation (curved arrows).
