The Balance between Mono- and NEDD8-Chains Controlled by NEDP1 upon DNA Damage Is a Regulatory Module of the HSP70 ATPase Activity

open access: yesCell Reports, 2019
Summary: Ubiquitin and ubiquitin-like chains are finely balanced by conjugating and de-conjugating enzymes. Alterations in this balance trigger the response to stress conditions and are often observed in pathologies.

The ubiquitin-proteasome system is required for African swine fever replication. [PDF]

open access: yesPLoS ONE, 2017
Several viruses manipulate the ubiquitin-proteasome system (UPS) to initiate a productive infection. Determined viral proteins are able to change the host's ubiquitin machinery and some viruses even encode their own ubiquitinating or deubiquitinating ...

TULIP2: An Improved Method for the Identification of Ubiquitin E3-Specific Targets

open access: yesFrontiers in Chemistry, 2019
Protein modification by Ubiquitin or Ubiquitin-like modifiers is mediated by an enzyme cascade composed of E1, E2, and E3 enzymes. E1s, or ubiquitin-activating enzymes, perform ubiquitin activation. Next, ubiquitin is transferred to ubiquitin-conjugating

The HIP2~ubiquitin conjugate forms a non-compact monomeric thioester during di-ubiquitin synthesis. [PDF]

open access: yesPLoS ONE, 2015
Polyubiquitination is a post-translational event used to control the degradation of damaged or unwanted proteins by modifying the target protein with a chain of ubiquitin molecules.

Structural Diversity of Ubiquitin E3 Ligase

open access: yesMolecules, 2021
The post-translational modification of proteins regulates many biological processes. Their dysfunction relates to diseases. Ubiquitination is one of the post-translational modifications that target lysine residue and regulate many cellular processes ...

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

open access: yes, 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 ...

UBE2G1 governs the destruction of cereblon neomorphic substrates

open access: yeseLife, 2018
The cereblon modulating agents (CMs) including lenalidomide, pomalidomide and CC-220 repurpose the Cul4-RBX1-DDB1-CRBN (CRL4CRBN) E3 ubiquitin ligase complex to induce the degradation of specific neomorphic substrates via polyubiquitination in ...

Pleiotropic Roles of a KEAP1-Associated Deubiquitinase, OTUD1

open access: yesAntioxidants, 2023
Protein ubiquitination, which is catalyzed by ubiquitin-activating enzymes, ubiquitin-conjugating enzymes, and ubiquitin ligases, is a crucial post-translational modification to regulate numerous cellular functions in a spatio–temporal-specific manner ...

Contributions of ubiquitin- and PCNA-binding domains to the activity of Polymerase η in Saccharomyces cerevisiae [PDF]

open access: yes, 2007
Bypassing of DNA lesions by damage-tolerant DNA polymerases depends on the interaction of these enzymes with the monoubiquitylated form of the replicative clamp protein, PCNA.

Determinants of Functionality in the Ubiquitin Conjugating Enzyme Family [PDF]

open access: yesStructure, 2004
The E2 enzymes are key enzymes in the ubiquitin and ubiquitin-like protein ligation pathways. To understand the functionality of the different E2 enzymes, we analyzed 190 protein sequences and 211 structures and electrostatic potentials. Key findings include: The ScUbc1 orthologs are defined by a C-terminal UBA domain. An N-terminal sequence motif that
