RBR E3 ubiquitin ligases: new structures, new insights, new questions [PDF]

open access: yes, 2014
The RBR (RING-BetweenRING-RING) or TRIAD [two RING fingers and a DRIL (double RING finger linked)] E3 ubiquitin ligases comprise a group of 12 complex multidomain enzymes.

Targeted Degradation of 53BP1 Using Ubiquitin Variant Induced Proximity

open access: yesBiomolecules, 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 ...

The role of Schizosaccharomyces pombe SUMO ligases in genome stability [PDF]

open access: yes, 2007
SUMOylation is a post-translational modification that affects a large number of proteins, many of which are nuclear. While the role of SUMOylation is beginning to be elucidated, it is clear that understanding the mechanisms that regulate the process is ...

E3 Ubiquitin Ligases as Cancer Targets and Biomarkers

open access: yesNeoplasia: 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 ...

Plant SUMO E3 Ligases: Function, Structural Organization, and Connection With DNA

open access: yesFrontiers 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.

Ligation and Ligases [PDF]

open access: yesCold Spring Harbor Protocols, 2019
DNA ligases are used chiefly to create novel combinations of nucleic acid molecules and to attach them to vectors before molecular cloning. They are either of bacterial origin or bacteriophage encoded and have different properties, as discussed here.

The ubiquitin E3/E4 ligase, UBE4A, fine-tunes protein ubiquitylation and accumulation at sites of DNA damage facilitating double-strand break repair [PDF]

open access: yes, 2018
Double-strand breaks (DSBs) are critical DNA lesions that robustly activate the elaborate DNA damage response (DDR) network. We identified a critical player in DDR fine-tuning - the E3/E4 ubiquitin ligase, UBE4A.

Role of RING-Type E3 Ubiquitin Ligases in Inflammatory Signalling and Inflammatory Bowel Disease

open access: yesMediators 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).

Evaluation of NAD(+)-dependent DNA ligase of mycobacteria as a potential target for antibiotics [PDF]

open access: yes, 2007
Mycobacteria contain genes for several DNA ligases, including ligA, which encodes a NAD+-dependent enzyme that has been postulated to be a target for novel antibacterial compounds.
