: Small ubiquitin-like modifiers (SUMOs) are polypeptides resembling ubiquitin that are covalently attached to specific lysine residue of target proteins through a specific enzymatic pathway. Sumoylation is now seen as a key posttranslational modification involved in many biological processes, but little is known about how this highly dynamic...

BACKGROUND: Small Ubiquitin-like MOdifier protein (SUMO) is a key regulator of nuclear functions but little is known regarding the role of the post-translational modification sumoylation outside of the nucleus, particularly in the Central Nervous System (CNS). METHODOLOGY/PRINCIPAL FINDINGS: Here, we report that the expression levels of...
BACKGROUND INFORMATION: Sumoylation is a key post-translational modification by which the Small Ubiquitin-like MOdifier (SUMO) polypeptide is covalently attached to specific lysine residues of substrate proteins through a specific enzymatic pathway. Although sumoylation participates in the regulation of nuclear homeostasis, the sumoylation...

Synapses are highly specialized structures that interconnect neurons to form functional networks dedicated to neuronal communication. During brain development, synapses undergo activity-dependent rearrangements leading to both structural and functional changes. Many molecular processes are involved in this regulation, including...

Sumoylation is a reversible post-translational modification essential to the modulation of neuronal function, including neurotransmitter release and synaptic plasticity. A tightly regulated equilibrium between the sumoylation and desumoylation processes is critical to the brain function and its disruption has been associated with several...
Fragile X-Syndrome (FXS) represents the most common inherited form of intellectual disability and the leading monogenic cause of Autism Spectrum Disorders. In most cases, this disease results from the absence of expression of the protein FMRP encoded by the FMR1 gene (Fragile X messenger ribonucleoprotein 1). FMRP is mainly defined as a...

Fragile X syndrome (FXS) is the most frequent inherited cause of intellectual disability and the best-studied monogenic cause of autism. FXS results from the functional absence of the fragile X mental retardation protein (FMRP) leading to abnormal pruning and consequently to synaptic communication defects. Here we show that FMRP is a substrate...
