Parkin-independent mitophagy controls chemotherapeutic response in cancer cells [PDF]
, 2017 Mitophagy is an evolutionarily conserved process that selectively targets impaired mitochondria for degradation. Defects in mitophagy are often associated with diverse pathologies, including cancer.

BioE3 identifies specific substrates of ubiquitin E3 ligases
Nature Communications, 2023 Hundreds of E3 ligases play a critical role in recognizing specific substrates for modification by ubiquitin (Ub). Separating genuine targets of E3s from E3-interactors remains a challenge. We present BioE3, a powerful approach for matching substrates to

A quantitative assay to monitor HSV-1 ICP0 ubiquitin ligase activity in vitro [PDF]
, 2015 The ubiquitin–proteasome system is an essential cellular process that plays a fundamental role in the regulation of protein stability. This pathway is tightly controlled by a sequential cascade of enzymatic steps that culminates in the formation of a ...

Global-genome Nucleotide Excision Repair Controlled by Ubiquitin/Sumo Modifiers
Frontiers in Genetics, 2016 Global-genome nucleotide excision repair (GG-NER) prevents genome instability by excising a wide range of structurally unrelated DNA base adducts and crosslinks induced by chemical carcinogens, ultraviolet (UV) radiation or intracellular metabolic by ...

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Methylated DNMT1 and E2F1 Are Targeted for Proteolysis by L3MBTL3 and CRL4DCAF5 Ubiquitin Ligase [PDF]
, 2018 Many non-histone proteins are lysine methylated and a novel function of this modification is to trigger the proteolysis of methylated proteins. Here, we report that the methylated lysine 142 of DNMT1, a major DNA methyltransferase that preserves ...

European Journal of Biochemistry, 1992 A novel form of rat liver DNA ligase (molecular mass 100 kDa) can be differentiated from DNA ligase I by several biochemical parameters. It is a more heat‐labile enzyme and unable to join bluntended DNA, even in the presence of poly(ethylene glycol) concentrations which stimulate such joining by DNA ligase I and T4 DNA ligase.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

USP15 targets ALK3/BMPR1A for deubiquitylation to enhance bone morphogenetic protein signalling [PDF]
, 2014 Protein kinase ALK3/BMPR1A mediates bone morphogenetic protein (BMP) signalling through phosphorylation and activation of SMADs 1/5/8. SMAD6, a transcriptional target of BMP, negatively regulates the BMP pathway by recruiting E3 ubiquitin ligases and ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
