Progress on Poxvirus E3 Ubiquitin Ligases and Adaptor Proteins

Frontiers in Immunology, 2021
Poxviruses have evolved a variety of innate immunity evasion mechanisms, some of which involve poxvirus-encoded E3 ubiquitin ligases and adaptor proteins.

Temperature adaptation of DNA ligases from psychrophilic organisms [PDF]

, 2019
DNA ligases operating at low temperatures have potential advantages for use in biotechnological applications. For this reason, we have characterized the temperature optima and thermal stabilities of three minimal Lig E-type ATP-dependent DNA ligase ...

E3-ligase knock down revealed differential titin degradation by autopagy and the ubiquitin proteasome system

Scientific Reports, 2021
The sarcomere protein titin is a major determinant of cardiomyocyte stiffness and ventricular distensibility. The constant mechanical stress on titin requires well-controlled protein quality control, the exact mechanisms of which have not yet been fully ...

NAD+-dependent DNA ligases of Mycobacterium tuberculosis and Streptomyces coelicolor [PDF]

, 2003
Sequencing of the genomes of Mycobacterium tuberculosis H37Rv and Streptomyces coelicolor A3(2) identified putative genes for an NAD+-dependent DNA ligase. We have cloned both open reading frames and overexpressed the protein products in Escherichia coli.

Expanding PROTACtable genome universe of E3 ligases

Nature Communications, 2023
Proteolysis-targeting chimera (PROTAC) and other targeted protein degradation (TPD) molecules that induce degradation by the ubiquitin-proteasome system (UPS) offer new opportunities to engage targets that remain challenging to be inhibited by ...

A capsid-encoded PPxY-motif facilitates adenovirus entry. [PDF]

, 2010
Viruses use cellular machinery to enter and infect cells. In this study we address the cell entry mechanisms of nonenveloped adenoviruses (Ads). We show that protein VI, an internal capsid protein, is rapidly exposed after cell surface attachment and ...

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 ...

Regulation of SCF Ubiquitin Ligases by Jab1/Csn5 and the Cop9 Signalosome [PDF]

, 2006
SCF ubiquitin ligases regulate the ubiquitin-dependent proteolysis of a myriad of substrate proteins, including p27, Cyclin E, and IkBa. To further gain insight into SCF regulation and function, we purified SCF from mammalian cells and found the Cop9 ...

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).

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.
