Deletion of proteasomal subunit S5a/Rpn10/p54 causes lethality, multiple mitotic defects and overexpression of proteasomal genes in Drosophila melanogaster [PDF]
, 2003 The regulatory complex of the 26S proteasome is responsible for the selective recognition and binding of multiubiquitinated proteins. It was earlier shown that the subunit S5a/Rpn10/p54 of the regulatory complex is the only cellular protein capable of ...

Advanced Science, EarlyView.Dysregulated protein modifications drive tumorigenesis. RINES, an E3 ubiquitin ligase, represses tumor cell proliferation and metastasis by facilitating RING domain‐dependent, ubiquitin–proteasome‐mediated degradation of STAT3 and MYC, which consequently restrains cancer stemness and oncogenic progression.

Early Retinal UCHL1 Dysregulation Coupled With Synaptic Loss Reflects Alzheimer's Disease Severity
Advanced Science, EarlyView.This study identifies synapse‐enriched deubiquitinase UCHL1 as an early Aβ‐responsive regulator of retinal synaptopathy in Alzheimer's disease. Retinal UCHL1 loss accompanies excitatory synapse degeneration, p75NTR activation, and neuroinflammation, and predicts Braak stage and cognitive decline. Aβ42 fibrils trigger synaptic and UCHL1 depletion before

TED1 Promotes the Assembly of SCFD3‐D14‐D53 to Reinforce Strigolactone Signaling in Rice
Advanced Science, EarlyView.This study identifies TED1 as a positive regulator of strigolactones (SL) signaling in rice. The ted1 mutants display dwarfism and increased tillering with significantly reduced SLs sensitivity. Through its longer C‐terminal region, TED1 interacts with D53 and D14 to promote the assembly of SCFD3‐D14‐D53, thereby facilitating the efficient ...

Advanced Science, EarlyView.ProMetNet introduces a biologically constrained deep learning framework for proteo‐metabolomic integration by embedding Reactome‐derived pathway topology into neural networks. It captures non‐linear molecular dependencies and pathway‐level metabolic reorganization, enabling interpretable discrimination.

Advanced Science, EarlyView.Glucocorticoids transcriptionally activate LCN2 expression via GR nuclear translocation. Secreted LCN2 binds MMP9 to degrade skeletal muscle ECM collagen, blocks integrin‐mediated mechanotransduction, bidirectionally disrupts muscle protein homeostasis, and reveals a novel target for steroid‐induced muscle atrophy.

Hypoxia adaptation in locusts aligns with proteasome capacity
Advances in Redox ResearchHypoxia disrupts protein homeostasis, but how proteostasis regulation contributes to population-specific hypoxia responses is not well understood. Migratory locusts (Locusta migratoria) inhabit diverse environments, and populations from contrasting ...

Purification, crystallization, and x-ray analysis of the yeast 20S proteasome
, 2005 Intracellular protein degradation is one of the most precisely regulated processes in living cells. The main component of the degradation machinery is the 20S proteasome present in eukaryotes as well as in prokaryotes.
