Reversible attachment of Cell-Penetrating Peptides for the efficient delivery of α-synuclein to HeLa cells and primary cortical neurons

The discovery of alpha-synuclein (a-syn) as the main component of Lewy Bodies (LBs), the pathological hallmarks of Parkinson's disease (PD), and the identification of mutations in the gene coding for a-syn in familial form of PD have reinforced the central ...

What does S-palmitoylation do to membrane proteins?

Françoise Gisou van der Goot Grunberg, Sanja Blaskovic, Mathieu Blanc

S-palmitoylation is post-translational modification, which consists in the addition of a C16 acyl chain to cytosolic cysteines and which is unique amongst lipid modifications in that it is reversible. It can thus, like phosphorylation or ubiquitination, ac ...

Palmitoylated calnexin is a key component of the ribosome-translocon complex

Françoise Gisou van der Goot Grunberg, Matteo Dal Peraro, Laurence Gouzi Abrami, Béatrice Kunz, Thomas Lemmin, Sanja Blaskovic

A third of the human genome encodes N-glycosylated proteins. These are co-translationally translocated into the lumen/membrane of the endoplasmic reticulum (ER) where they fold and assemble before they are transported to their final destination. Here, we s ...

Molecular Mechanisms Underlying Hyaline Fibromatosis Syndrome

Julie Deuquet Ariosa

Hyaline Fibromatosis Syndrome (HFS) is a rare inherited disease that is characterized by an accumulation of an unidentified hyaline material, largely affecting connective tissues. Patients afflicted with HFS present a wide range of clinical symptoms such a ...

Investigation of novel calcium-related events as suspected contributors to neurodegeneration

Nikita Rudinskiy

Calcium regulates neuronal signaling and viability through a vast range of cellular and molecular mechanisms. However, many details of these mechanisms still remain to be elucidated. It is believed that calcium-related pathways may comprise promising thera ...

Palmitoylation cycles and regulation of protein function (Review)

Steinunn Baekkeskov Hanahan

The efficacy and success of many cellular processes is dependent on a tight orchestration of proteins trafficking to and from their site(s) of action in a time-controlled fashion. Recently, a dynamic cycle of palmitoylation/de-palmitoylation has been shown ...

Indo-1 derivatives for local calcium sensing

Kai Johnsson, Annina Aebischer, Cindy Fellay

The role of calcium in signal transduction relies on the precise spatial and temporal control of its concentration. The existing means to detect fluctuations in Ca2+ concentrations with adequate temporal and spatial resolution are limited. We introduce her ...

A palmitoylation cycle dynamically regulates partitioning of the GABA-synthesizing enzyme GAD65 between ER-Golgi and post-Golgi membranes

Steinunn Baekkeskov Hanahan

GAD65, the smaller isoform of the enzyme glutamic acid decarboxylase, synthesizes GABA for fine-tuning of inhibitory neurotransmission. GAD65 is synthesized as a soluble hydrophilic protein but undergoes a hydrophobic post-translational modification and be ...

Lipid-transfer proteins in biosynthetic pathways

Compartmentalization is a defining feature of eukaryotic cells that allows the spatial segregation of different functions, such as protein and lipid synthesis, and ensures their fidelity and efficiency. This imposes the need for an intense flux of metaboli ...

Expression of a dominant negative form of Daxx in vivo rescues motoneurons from Fas (CD95)-induced cell death

Fas-induced death of motoneurons in vitro has been shown to involve two signaling cascades that act together to execute the death program: a Fas-Daxx-ASK-1-p38 kinase-nNOS branch, which controls transcriptional and post-translational events, and the second ...
