ADP‐ribosylation: An emerging regulator of the epigenome

Molecular Oncology, EarlyView.
ADP‐ribosylation has emerged as a dynamic epigenetic signaling mechanism that modifies histones and chromatin‐associated proteins. Through coordinated PARylation and MARylation, it integrates with other histone modifications to regulate chromatin structure, transcription factor activity, and gene expression, influencing genome function and disease ...

SARS-CoV-2-host and interactions: the dual roles of E3 ubiquitin ligases and ubiquitin-like modification mechanisms in viral infection

Frontiers in Immunology
Following the global outbreak of the COVID-19 pandemic, the interactions between SARS-CoV-2 and host cells have attracted widespread attention. As crucial intracellular enzymes, E3 ubiquitin ligases are involved in numerous physiological processes ...

Table_1_How to Inactivate Human Ubiquitin E3 Ligases by Mutation.DOCX

, 2020
E3 ubiquitin ligases are the ultimate enzymes involved in the transfer of ubiquitin to substrate proteins, a process that determines the fate of the modified protein.

Unraveling the epigenetic code in cancer cell–tumor microenvironment crosstalk

Molecular Oncology, EarlyView.
Epigenetic regulation is a key driver of cancer development and progression. Diverse epigenetic alterations in cancer cells and components of the tumor microenvironment (TME) orchestrate their communication through multiple mechanisms. We discuss how the epigenetic code coordinates bidirectional cancer cell–TME crosstalk to promote cancer progression ...

Crystal structure of UBA2ufd-Ubc9: insights into E1-E2 interactions in sumo pathways [PDF]

, 2010
Canonical ubiquitin-like proteins (UBLs) such as ubiquitin, Sumo, NEDD8, and ISG15 are ligated to targets by E1-E2-E3 multienzyme cascades. The Sumo cascade, conserved among all eukaryotes, regulates numerous biological processes including protein ...

Arginine methylation as a regulatory ratchet in cancer: From substrate selection to malignant‐state stabilization

Molecular Oncology, EarlyView.
Arginine methylation can be viewed as a persistence‐prone post‐translational modification regulated by a network of PRMTs. Competitive and compensatory interactions among PRMTs can redistribute methylation across substrate pools shaped by sequence, structural, spatial, and environmental layers, reinforcing RNA‐processing, chromatin, and signaling ...

Bioinformatics analysis identifies several intrinsically disordered human E3 ubiquitin-protein ligases [PDF]

PeerJ, 2016
The ubiquitin-proteasome system targets misfolded proteins for degradation. Since the accumulation of such proteins is potentially harmful for the cell, their prompt removal is important.

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 ...

TRIM5α as an E3 ubiquitin ligase

The FASEB Journal, 2009
Human immunodeficiency virus type1 (HIV‐1) efficiently infects susceptible cells and causes acquired immunodeficiency syndrome (AIDS) in humans. Although HIV can also enter the cells of Old World monkeys, it encounters a block before reverse transcription.
