Emerging roles of the HECT E3 ubiquitin ligases in gastric cancer

open access: yesPathology and Oncology Research, 2023
Gastric cancer (GC) is one of the most pernicious gastrointestinal tumors with extraordinarily high incidence and mortality. Ubiquitination modification of cellular signaling proteins has been shown to play important roles in GC tumorigenesis ...

Differential requirement for BRCA1-BARD1 E3 ubiquitin ligase activity in DNA damage repair and meiosis in the Caenorhabditis elegans germ line.

open access: yesPLoS Genetics, 2023
The tumor suppressor BRCA1-BARD1 complex regulates many cellular processes; of critical importance to its tumor suppressor function is its role in genome integrity.

Activity-based probe profiling of RNF12 E3 ubiquitin ligase function in Tonne-Kalscheuer syndrome

open access: yesLife Science Alliance, 2022
The authors use photocrosslinking activity-based probes to monitor RNF12/RLIM E3 ubiquitin ligase activity and report the impact of Tonne-Kalscheuer syndrome (TOKAS) patient variants on catalysis.

PROTACs: A novel strategy for cancer drug discovery and development

open access: yesMedComm, 2023
Proteolysis targeting chimera (PROTAC) technology has become a powerful strategy in drug discovery, especially for undruggable targets/proteins. A typical PROTAC degrader consists of three components: a small molecule that binds to a target protein, an ...

RBR E3‐ligases at work [PDF]

open access: yesThe EMBO Reports, 2014
The RING-in-between-RING (RBR) E3s are a curious family of ubiquitin E3-ligases, whose mechanism of action is unusual in several ways. Their activities are auto-inhibited, causing a requirement for activation by protein-protein interactions or posttranslational modifications.

CUL4-DDB1-CDT2 E3 Ligase Regulates the Molecular Clock Activity by Promoting Ubiquitination-Dependent Degradation of the Mammalian CRY1. [PDF]

open access: yesPLoS ONE, 2015
The CUL4-DDB1 E3 ligase complex serves as a critical regulator in various cellular processes, including cell proliferation, DNA damage repair, and cell cycle progression.

Activity-based E3 ligase profiling uncovers an E3 ligase with esterification activity [PDF]

open access: yesNature, 2018
Ubiquitination is initiated by transfer of ubiquitin (Ub) from a ubiquitin-activating enzyme (E1) to a ubiquitin-conjugating enzyme (E2), producing a covalently linked intermediate (E2-Ub) 1 . Ubiquitin ligases (E3s) of the 'really interesting new gene' (RING) class recruit E2-Ub via their RING domain and then mediate direct transfer of ubiquitin to ...

The EHEC type III effector NleL is an E3 ubiquitin ligase that modulates pedestal formation. [PDF]

open access: yesPLoS ONE, 2011
Enterohemorrhagic Escherichia coli (EHEC) O157:H7 causes hemorrhagic colitis and may result in potentially fatal hemolytic uremia syndrome in humans. EHEC colonize the intestinal mucosa and promote the formation of actin-rich pedestals via translocated ...

Identification of a MicroRNA‐E3 Ubiquitin Ligase Regulatory Network for Hepatocyte Death in Alcohol‐Associated Hepatitis

open access: yesHepatology Communications, 2021
We aimed to identify a microRNA (miRNA)‐E3 ubiquitin ligase regulatory network for protein substrates enriched in cell death pathways and investigate the underlying molecular mechanisms in alcohol‐associated hepatitis (AH).

MDM2 E3 ligase activity is essential for p53 regulation and cell cycle integrity.

open access: yesPLoS Genetics, 2022
MDM2 and MDM4 are key regulators of p53 and function as oncogenes when aberrantly expressed. MDM2 and MDM4 partner to suppress p53 transcriptional transactivation and polyubiquitinate p53 for degradation.
