Expanding PML's functional repertoire through post-translational mechanisms

Front Biosci (Landmark Ed). 2009 Jan 1;14:2293-306. doi: 10.2741/3380.


Post-translational modifications, such as acetylation and ubiquitination, can greatly expand the functionality of a particular protein. The promyelocytic leukemia (PML) protein is a functionally promiscuous protein with proposed roles in many cellular processes. Its cellular headquarters are the macromolecular structures termed PML nuclear bodies. Post-translational modification of PML is emerging as a defining feature of this protein that regulates its physiological consequences. This review will highlight the expansion of our knowledge about the post-translational modifications of PML.
