A schematic diagram of PML functional domains. All PML isoforms share the same N-terminal 418 amino acids, which contain RING (R), B-Box1 (B1), B-Box1 (B2) and coiled coil (CC) domains. Nuclear PML isoforms share the same N-terminal 552 amino acids, which in addition to RBCC, contains a nuclear localization signal (NLS) and a SUMO-interacting motif (SIM) (66) present in PML isoforms I–V. Only PMLI contains a putative nuclear export signal (NES) at its C-terminus
