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.

GTPase Rac1 et ubiquitination [PDF]
Cette thèse a été consacrée à l étude de la régulation par ubiquitination d une protéine de signalisation cellulaire, la GTPase Rac1. J ai montré que l ubiquitination dégradative de Rac1 affecte peu son variant d épissage Rac1b, et qu elle requiert l ...

Insights into non-proteinaceous ubiquitination [PDF]
Ubiquitination plays a key role in the regulation of numerous diverse cellular functions. This process involves the covalent attachment of ubiquitin to protein substrates by a cascade of enzymes.

Activation of the main DNA interstrand crosslink repair pathway in higher eukaryotes requires mono-ubiquitination of FANCI and FANCD2 by FANCL, the E3 ligase subunit of the Fanconi anemia core complex. FANCI and FANCD2 form a stable complex; however, the

The Expanding Universe of Ubiquitin and Ubiquitin-Like Modifiers [PDF]
The post-translation addition of ubiquitin (Ub) and structurally related polypeptide modifiers to other intracellular constituents is now known to be an important intermediate driving a wide assortment of metabolic and regulatory processes in plants. Although the most common targets are other proteins, conjugation of specific modifiers to lipids and ...

ABSTRACT Astrocyte reactivity critically shapes neuroinflammatory outcomes after ischemic stroke, yet the upstream regulators governing astrocyte state transitions remain incompletely defined. Here, we identify the immunoproteasome subunit low molecular weight protein 2 (LMP2) as an important modulator of astrocyte functional remodeling following ...

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 ...

In renal calcium oxalate stone formation, G6PC downregulation leads to lactate accumulation. This lactate mediates CBP/p300‐dependent lactylation of SNAIL1 at K206, promoting its nuclear translocation. Nuclear SNAIL1 activates the TGF‐β/SMAD3 pathway, driving epithelial‐mesenchymal transition and fibrosis, which ultimately facilitates crystal ...
