[[http://www.uniprot.org/uniprot/SUMO1_HUMAN SUMO1_HUMAN]] Ubiquitin-like protein that can be covalently attached to proteins as a monomer or a lysine-linked polymer. Covalent attachment via an isopeptide bond to its substrates requires prior activation by the E1 complex SAE1-SAE2 and linkage to the E2 enzyme UBE2I, and can be promoted by E3 ligases such as PIAS1-4, RANBP2 or CBX4. This post-translational modification on lysine residues of proteins plays a crucial role in a number of cellular processes such as nuclear transport, DNA replication and repair, mitosis and signal transduction. Involved for instance in targeting RANGAP1 to the nuclear pore complex protein RANBP2. Polymeric SUMO1 chains are also susceptible to polyubiquitination which functions as a signal for proteasomal degradation of modified proteins. May also regulate a network of genes involved in palate development.<ref>PMID:9019411</ref> <ref>PMID:9162015</ref> <ref>PMID:18538659</ref> <ref>PMID:18408734</ref>

The interactions between SUMO proteins and SUMO-interacting motif (SIM) in nuclear bodies formed by the promyelocytic leukemia (PML) protein (PML-NBs) have been shown to be modulated by either phosphorylation of the SIMs or acetylation of SUMO proteins. However, little is known about how this occurs at the atomic level. In this work, we examined the role that acetylation of SUMO1 plays on its binding to the phosphorylated SIMs (phosphoSIMs) of PML and Daxx. Our results demonstrate that SUMO1 binding to the phosphoSIM of either PML or Daxx is dramatically reduced by acetylation at either K39 or K46. However, acetylation at K37 only impacts binding to Daxx. Structures of acetylated SUMO1 variants bound to the phosphoSIMs of PML and Daxx demonstrate that there is structural plasticity in SUMO-SIM interactions. The plasticity observed in these structures provides a robust mechanism for regulating SUMO-SIM interactions in PML-NBs using signaling generated post-translational modifications.
