Ubiquitin Ligases at the Heart of Skeletal Muscle Atrophy Control
Molecules, 2021 Skeletal muscle loss is a detrimental side-effect of numerous chronic diseases that dramatically increases mortality and morbidity. The alteration of protein homeostasis is generally due to increased protein breakdown while, protein synthesis may also be

Targeted Degradation of 53BP1 Using Ubiquitin Variant Induced Proximity
Biomolecules, 2022 In recent years, researchers have leveraged the ubiquitin-proteasome system (UPS) to induce selective degradation of proteins by E3 ubiquitin ligases, which has great potential as novel therapeutics for human diseases, including cancer and ...

Plant SUMO E3 Ligases: Function, Structural Organization, and Connection With DNA
Frontiers in Plant Science, 2021 Protein modification by the small ubiquitin-like modifier (SUMO) plays an important role in multiple plant processes, including growth, development, and the response to abiotic stresses.

E3 Ubiquitin Ligases as Cancer Targets and Biomarkers
Neoplasia: An International Journal for Oncology Research, 2006 E3 ubiquitin ligases are a large family of proteins that are engaged in the regulation of the turnover and activity of many target proteins. Together with ubiquitinactivating enzyme El and ubiquitin-conjugating enzyme E2, E3 ubiquitin ligases catalyze ...

Role of RING-Type E3 Ubiquitin Ligases in Inflammatory Signalling and Inflammatory Bowel Disease
Mediators of Inflammation, 2020 Ubiquitination is a three-step enzymatic cascade for posttranslational protein modification. It includes the ubiquitin-activating enzyme (E1), ubiquitin-conjugating enzyme (E2), and ubiquitin ligase (E3).

Tau affects P53 function and cell fate during the DNA damage response [PDF]
Communications Biology 3, 245 (2020), 2020 Cells are constantly exposed to DNA damaging insults. To protect the organism, cells developed a complex molecular response coordinated by P53, the master regulator of DNA repair, cell division and cell fate. DNA damage accumulation and abnormal cell fate decision may represent a pathomechanism shared by aging-associated disorders such as cancer and ...

Exploring PROTAC cooperativity with coarse-grained alchemical methods [PDF]
, 2022 Proteolysis targeting chimera (PROTAC) is a novel drug modality that facilitates the degradation of a target protein by inducing proximity with an E3 ligase. In this work, we present a new computational framework to model the cooperativity between PROTAC-E3 binding and PROTAC-target binding principally through protein-protein interactions (PPIs ...

Runaway Transition in Irreversible Polymer Condensation with Cyclisation [PDF]
, 2022 The process of polymer condensation, i.e. the formation of bonds between reactive end-groups, is ubiquitous in both industry and biology. Here we study generic systems undergoing polymer condensation in competition with cyclisation. Using a generalised Smoluchowski theory, molecular dynamics simulations and experiments using DNA and T4 ligase, we find ...
