The ataxia (axJ) mutation causes abnormal GABAA receptor turnover in mice [PDF]
Ataxia represents a pathological coordination failure that often involves functional disturbances in cerebellar circuits. Purkinje cells (PCs) characterize the only output neurons of the cerebellar cortex and critically participate in regulating motor ...

This study unveiled that METTL14 mediates m6A modification of WDR72 mRNA to stabilize and enhance WDR72 expression, which disrupts TRIM31‐mediated ubiquitination of CBX8 protein and retards its degradation, finally the elevated CBX8 contributes to tumor stemness.

Proteasome-associated HECT-type ubiquitin ligase activity is required for plant immunity.
Regulated degradation of proteins by the 26S proteasome plays important roles in maintenance and signalling in eukaryotic cells. Proteins are marked for degradation by the action of E3 ligases that site-specifically modify their substrates by adding ...

Neurodegenerative stress related mitochondrial proteostasis [PDF]
1.1 Background: Mitochondria are the main site of energy production in most cells. Furthermore, they are involved in a multitude of other essential cellular processes, such as regulating the cellular calcium pool, lipid metabolism and programmed cell ...

Structural Polymorphism of polyG Inclusions Revealed by In Situ Cryo‐Electron Tomography
Correlative cryo‐electron tomography in primary cortical neurons and NIID mouse brain tissue reveals that polyG inclusions are interconnected ribbon‐like assemblies rather than canonical amyloid fibrils. Multiple compartment‐specific ribbon states show distinct 26S proteasome accessibility, while cytoplasmic ribbons contact and deform ER‐like ...

Proteasome dysfunction in aged human α-synuclein transgenic mice
A deficit in proteasome function in Parkinson's disease has been speculated. We characterized the ubiquitin–proteasome system in three regions of brain from transgenic and nontransgenic littermates.

ZBTB11 is identified as an oncogenic transcription factor that activates FBXO28 in breast cancer. FBXO28 promotes K48‐linked ubiquitination and degradation of MST1, suppressing Hippo signaling and enhancing epithelial–mesenchymal transition and metastasis. This transcription‐to‐ubiquitination cascade defines a prognostic biomarker axis and highlights a
