Proteomics insights into Infantile Neuronal Ceroid Lipofuscinosis (CLN1) point to the involvement of palmitoylation in the disease

Project description:Mutations in the depalmitoylation enzyme, palmitoyl protein thioesterase (PPT1), result in the early onset neurodegenerative disease known as Infantile Neuronal Ceroid Lipofuscinosis. Here, we provide proteomic evidence suggesting that PPT1 deficiency could be considered as a ciliopathy. An unbiased proteomic analysis of membranal brain proteins from neonate Ppt1 knock out and control mice revealed a list of 88 proteins with different expression levels. Among them, we identified Rab3IP, which is known to work in concert with Rab8 and Rab11 to regulated proper ciliogenesis. Surprisingly, PPT1 was observed to localize to cilia. Indeed, an unbiased proteomics analysis on isolated cilia revealed 660 proteins, which differed in their abundance between wild type and Ppt1 knock out. We demonstrate here that Rab3IP, Rab8 and Rab11 are palmitoylated proteins, and palmitoylation of Rab11 is required for proper intracellular localization. Most interestingly, cells and tissues from Ppt1-/- exhibited less ciliated cells and abnormally longer cilia with both acetylated tubulin and Rab3IP mis-distributed along the length of cilia. Overall, our results suggest a novel link between palmitoylated proteins, cilia organization and the pathophysiology of Neuronal Ceroid Lipofuscinosis.

CLN3 patients with differing progression of the disease

Project description:Mutations in the CLN3 gene lead to juvenile neuronal ceroid lipofuscinosis, a pediatric neurodegenerative disorder characterized by visual loss, epilepsy and psychomotor deterioration. Although most CLN3 patients carry the same 1 kb deletion in the CLN3 gene, their disease phenotype can be variable. The aims of this study were (1) to identify genes that are dysregulated in CLN3 disease regardless of the clinical course that could be useful as biomarkers, and (2) to find modifier genes that affect the progression rate of the disease. Genome-wide expression profiling was performed in 8 CLN3 patients, homozygous for the 1 kb deletion, with different disease progression and compared to seven age and gender matched controls.

Transcriptional control of lysosomal homeostasis by the disease-related CLN3 membrane protein

Project description:CLN3 is a type II transmembrane protein localized in the late endosomal/lysosomal compartment. A deficiency of CLN3 leads to the development of a certain type of Neuronal Ceroid Lipofuscinosis, a neurodegenerative disorder of childhood caused by aggregation of undegraded material in the lysosomal compartment. Cultured, immortalized wild type and Cln3(Δex7/8) cerebellar granule cells were used in this project to determine the influence of Cln3 deficiency on the proteome of the lysosomal compartment. For this purpose, cells were labelled by stable amino acid labelling in cell culture and lysosomes were isolated by magnetic beads.
