Key Points
-
SUMOylation is a reversible covalent post-translational modification that involves the conjugation of a member of the small ubiquitin-like modifier (SUMO) family to lysine residues in target proteins. SUMO proteins are conjugated by an enzymatic pathway and can mediate a diverse range of subsequent fates for substrate proteins.
-
In a number of systems, both covalent attachment of SUMO and non-covalent binding to SUMO contribute to functional outcomes. Recently, a number of SUMO interacting motifs (SIMs) have been reported that allow proteins to bind to SUMO.
-
SUMOylation is best characterized in the nucleus; however, numerous extranuclear substrates have also been reported. Potential roles for extranuclear SUMOylation include the regulation of G-protein, kinase and phosphatase signalling, axonal mRNA trafficking, and mitochondrial fission and apoptosis.
-
At the plasma membrane, SUMOylation has been implicated in the regulation of a number of key proteins, including glucose transporters, potassium channels and glutamate receptors.
-
SUMOylation has a central role in synapse formation through the modification of the transcription factor MEF2A. Active MEF2A inhibits synapse formation, and the activity-dependent interplay between SUMOylation, phosphorylation and acetylation of MEF2A can suppress this inhibition.
-
A role for SUMO in various neurological disorders is becoming increasingly well documented. Numerous forms of neuronal inclusions stain positive for SUMO family members, and proteins involved in the pathogenesis of disorders such as Huntington's disease, Parkinson's disease and Alzheimer's disease have been reported to be SUMO substrates.
-
SUMO features in various cellular stress responses. For example, large changes in protein SUMOylation have been reported upon cellular oxidative stress and ischemia.
Abstract
Post-translational protein modifications are integral components of signalling cascades that enable cells to efficiently, rapidly and reversibly respond to extracellular stimuli. These modifications have crucial roles in the CNS, where the communication between neurons is particularly complex. SUMOylation is a post-translational modification in which a member of the small ubiquitin-like modifier (SUMO) family of proteins is conjugated to lysine residues in target proteins. It is well established that SUMOylation controls many aspects of nuclear function, but it is now clear that it is also a key determinant in many extranuclear neuronal processes, and it has also been implicated in a wide range of neuropathological conditions.

Glossary
- Ubiquitylation
-
The covalent attachment of the 76-amino-acid protein ubiquitin to lysine residues in target proteins. Ubiquitylation is typically involved in the sorting of proteins for degradation, although there are numerous exceptions.
- Paralogue
-
Either of a pair of genes that derive from the same ancestral gene.
- Consensus motif
-
A sequence that is conserved among proteins that undergo a particular modification within that sequence. Consensus motifs also exist for several non-covalent interactions.
- Isopeptidase
-
An enzyme that specifically recognizes isopeptide bonds and cleaves them. SENPs have SUMO-specific isopeptidase activity, and cleave SUMO from SUMO-conjugated substrates.
- Deconjugation
-
The removal of covalently attached SUMO from the substrate.
- G protein
-
A heterotrimeric GTP-binding protein that interacts with cell-surface receptors, often stimulating or inhibiting the activity of a downstream enzyme. G proteins consist of three subunits: the α subunit, which contains the guanine-nucleotide-binding site, and the β and γ subunits, which function as a heterodimer.
- Synaptosomes
-
Discrete structures formed from the synaptic terminals upon brain homogenization in which the main structural presynaptic features are preserved. These structures retain the ability take up, store and release neurotransmitters.
- Nucleocytoplasmic shuttling
-
Bidirectional protein transport between the cytoplasm and the nuclear matrix through the nuclear pore complex.
- Synaptic plasticity
-
A cellular process that results in lasting changes in the efficacy of neurotransmission.
- Yeast two-hybrid screen
-
A system used to determine whether proteins directly interact. It involves the use of plasmids that encode two hybrid proteins, one of which is fused to the GAL4 DNA-binding domain and the other of which is fused to the GAL4 activation domain. The two proteins are expressed together in yeast and, if they interact, the resulting complex will drive the expression of a reporter gene, commonly β-galactosidase.
- Metabotropic glutamate receptors
-
A family of eight GPCRs that are activated by glutamate. They are classified into three groups (I–III) on the basis of their pharmacological properties and their downstream effector cascades.
- Dendritic claw
-
A postsynaptic differentiation of dendrites that is morphologically characteristic. In the cerebellum, granule cells develop dendritic claws with which they form synapses with mossy-fibre terminals.
- α-synuclein
-
A neuronal protein of unknown function that is detected mainly in presynaptic terminals. It can aggregate to form insoluble fibrils known as Lewy bodies, which are observed in pathological conditions such as Parkinson's disease.
- Proteasome
-
The protein complex that is responsible for degrading intracellular proteins that have been tagged for destruction by the conjugation of ubiquitin.
- Oxidative stress
-
A disturbance in the oxidant–antioxidant balance in favour of the former, leading to potential cellular damage including the mutation of DNA bases, protein oxidation and the generation of lipid peroxidation products.
- Amyloid-β (Aβ)
-
A peptide of size 39–43 amino acids that is the main constituent of amyloid plaques in the brain of Alzheimer's disease patients. These plaques are composed of a tangle of regularly ordered fibrillar aggregates called amyloid fibres. Among these heterogeneous peptide molecules, Aβ40 and Aβ42 are the most common isoforms. Aβ42 is the most fibrillogenic peptide and is thus associated with disease states.
- Reactive oxygen species
-
(ROS). These include free radicals, peroxides and oxygen ions. ROS form as a natural byproduct of oxidative phosphorylation in the mitochondria. Under pathological conditions, ROS levels can increase significantly, resulting in serious cellular damage. Cells normally defend themselves against ROS damage by the action of enzymes such as catalases and superoxide dismutase.
- Excitotoxicity
-
A pathological process by which neurons are damaged and killed by the overactivation of glutamate receptors.
- Long-term potentiation
-
(LTP). A form of synaptic plasticity that results in a long-lasting increase in the strength of synaptic transmission.
- Long-term depression
-
(LTD). A form of synaptic plasticity that results in a longlasting decrease in the strength of synaptic transmission.
