PML: a zinc-finger protein that can regulate transcription and can localize to nuclear bodies. Cytoplasmic forms regulate glycolysis by inhibiting the tetrameric form of PKM2. Together with SATB1, involved in local chromatin-loop remodeling and gene expression regulation at the MHC-I locus. Interacts with SIRT1, TOPBP1, TRIM27 and TRIM69. Sumoylated forms interact with SATB1 and localize to the PML nuclear bodies. Sumoylation on three sites is required for nuclear body formation. Sumoylation on Lys-160 is a prerequisite for sumoylation on Lys-65. The B1 box and the RING finger are also required for localization to nuclear bodies. May play an important role in recruitment of ELF4 into PML nuclear bodies. A chromosomal aberration involving PML can cause acute promyelocytic leukemia (APL). Seven alternatively-spliced human isoforms have been reported.
