Effect of ATG12–ATG5-ATG16L1 autophagy E3-like complex on the ability of LC3/GABARAP proteins to induce vesicle tethering and fusion
(Springer, 2023-02)
In macroautophagy, the autophagosome (AP) engulfs portions of cytoplasm to allow their lysosomal degradation. AP formation in humans requires the concerted action of the ATG12 and LC3/GABARAP conjugation systems. The ...
Conformational stabilization as a strategy to prevent nucleophosmin mislocalization in leukemia
(Nature Research, 2017-10-24)
Nucleophosmin (NPM) is a nucleolar protein involved in ribosome assembly and cell homeostasis. Mutations in the C-terminal domain of NPM that impair native folding and localization are associated with acute myeloid leukemia ...
Partitioning of liquid-ordered/liquid-disordered membrane microdomains induced by the fluidifying effect of 2-hydroxylated fatty acid derivatives
(2013-06-18)
[EN] Cellular functions are usually associated with the activity of proteins and nucleic acids. Recent studies have shown that lipids modulate the localization and activity of key membrane-associated signal transduction ...
Human ATG3 binding to lipid bilayers: role of lipid geometry, and electric charge
(Nature Publishing, 2017-11-15)
Specific protein-lipid interactions lead to a gradual recruitment of AuTophaGy-related (ATG) proteins to the nascent membrane during autophagosome (AP) formation. ATG3, a key protein in the movement of LC3 towards the ...
Triacylglycerol mimetics regulate membrane interactions of glycogen branching enzyme: implications for therapy
(Elsevier, 2017-06-19)
Adult polyglucosan body disease (APBD) is a neurological disorder characterized by adult-onset neurogenic bladder, spasticity, weakness, and sensory loss. The disease is caused by aberrant glycogen branching enzyme (GBE) ...
Interaction of the LC3/GABARAP autophagy proteins with membranes: Exploring the effects of ceramide
(2023-07-21)
La macroautofagia es un proceso que ocurre en los organismos eucariotas, se caracteriza por la formación del autofagosoma, una estructura de doble membrana encargada de rodear los componentes celulares que se degradan ...
Lipid-protein interactions in autophagy: Exploring the role of LC3/GABARAP-family members
(2022-07-19)
La autofagia es una vía de degradación conservada entre los eucariotas caracterizada por la formación de una vesícula de doble membrana (autofagosoma) alrededor de lo que se quiere degradar para su posterior eliminación ...
Pb(II) Induces Scramblase Activation and Ceramide-Domain Generation in Red Blood Cells
(Nature Publishing, 2018-05-10)
The mechanisms of Pb(II) toxicity have been studied in human red blood cells using confocal microscopy, immunolabeling, fluorescence-activated cell sorting and atomic force microscopy. The process follows a sequence of ...
Mixing brain cerebrosides with brain ceramides, cholesterol and phospholipids
(Nature Publishing, 2019-09-16)
The properties of bilayers composed of pure brain cerebroside (bCrb) or of binary mixtures of bCrb with brain ceramide, cholesterol, egg phosphatidylcholine or brain sphingomyelin have been studied using a combination of ...
Patches and Blebs: A Comparative Study of the Composition and Biophysical Properties of Two Plasma Membrane Preparations from CHO Cells
(MDPI, 2020-04-10)
This study was aimed at preparing and characterizing plasma membranes (PM) from Chinese Hamster Ovary (CHO) cells. Two methods of PM preparation were applied, one based on adhering cells to a poly-lysine-coated surface, ...
