Investigation of two Arabidopsis RING-type E3 ligases, KEG and XBAT32.

open access: yes, 2014
E3 ubiquitin ligases are a family of proteins that facilitate the covalent attachment of ubiquitin onto target proteins. Protein activity, function, and stability are influenced by ubiquitination and consequently ubiquitination has a major impact on ...

TOLLIP Inhibits Psoriasis Progression via Suppressing PKM2‐Mediated Glycolysis in Keratinocytes

open access: yesAdvanced Science, EarlyView.
In this study, we identify TOLLIP as a critical regulator of psoriasis pathogenesis through its modulation of glycolytic metabolism. Our findings establish the TOLLIP‐PKM2‐glycolysis axis as a key mechanism linking metabolic reprogramming to psoriasis pathogenesis, and propose TOLLIP as a promising therapeutic target.

Loss of E3 Ubiquitin Ligase RINES via CpG Methylation Relieves Suppression of STAT3 and MYC, Facilitating Multiple Tumorigeneses

open access: yesAdvanced 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.

Trim17, novel E3 ubiquitin-ligase, initiates neuronal apoptosis [PDF]

open access: yes, 2010
Accumulating data indicate that the ubiquitin-proteasome system controls apoptosis by regulating the level and the function of key regulatory proteins. In this study, we identified Trim17, a member of the TRIM/RBCC protein family, as one of the critical ...

Mitochondrial SLC25A46 Rewires Fatty Acid Oxidation to Promote Cell Proliferation and Ferroptosis Evasion in Ovarian Cancer by Stabilizing CACT

open access: yesAdvanced Science, EarlyView.
Mitochondrial SLC25A46 is upregulated in ovarian cancer (OC) and correlates with poor prognosis. SLC25A46 stabilizes CACT to activate fatty acid oxidation, increasing ATP and NADPH production to drive cell proliferation and ferroptosis evasion. SLC25A46 silencing sensitizes OC cells to ferroptosis and carboplatin, offering a promising therapeutic ...

SARS-CoV-2-host and interactions: the dual roles of E3 ubiquitin ligases and ubiquitin-like modification mechanisms in viral infection

open access: yesFrontiers in Immunology
Following the global outbreak of the COVID-19 pandemic, the interactions between SARS-CoV-2 and host cells have attracted widespread attention. As crucial intracellular enzymes, E3 ubiquitin ligases are involved in numerous physiological processes ...

TRIM5α as an E3 ubiquitin ligase

open access: yesThe FASEB Journal, 2009
Human immunodeficiency virus type1 (HIV‐1) efficiently infects susceptible cells and causes acquired immunodeficiency syndrome (AIDS) in humans. Although HIV can also enter the cells of Old World monkeys, it encounters a block before reverse transcription.

Essential Roles of E3 Ubiquitin Ligases in p53 Regulation

open access: yes, 2017
The ubiquitination pathway and proteasomal degradation machinery dominantly regulate p53 tumor suppressor protein stability, localization, and functions in both normal and cancerous cells. Selective E3 ubiquitin ligases dominantly regulate protein levels

Porcine Deltacoronavirus M Protein Binds NLRP3 to Promote Inflammasome Assembly via Competition with TRIM31

open access: yesAdvanced Science, EarlyView.
Porcine deltacoronavirus (PDCoV) infection induces severe intestinal inflammation and acute diarrhea in piglets, yet the molecular mechanism remains incompletely understood. The M protein activates NLRP3 inflammasome through dual mechanisms: direct binding to the NLRP3 LRR domain and disruption of TRIM31‐mediated K48‐linked ubiquitination.
