RANBP2 of the nuclear pore complex SUMOylates PML with SUMO2 at lysine-65, lysine-160, and lysine-490 (Kamitani et al. 1998, Tatham et al. 2005). RANBP2 contains both a binding site for SUMO1 and a binding site for UBE2I (Tatham et al. 2005). The binding site for UBE2I participates in SUMOylation of PML with SUMO2. SUMO2 colocalizes significantly with PML bodies (Vertegaal et al. 2004).
