A conserved ubiquitin ligase of the nuclear envelope/endoplasmic reticulum that functions in both ER-associated and Mat a2 repressor degradation [PDF]

open access: yes, 2001
Substrate discrimination in the ubiquitin–proteasome system is believed to be dictated by specific combinations of ubiquitin–protein ligases (E3s) and ubiquitin-conjugating enzymes (E2s).

MDC1 mediates Pellino recruitment to sites of DNA double-strand breaks

open access: yesLife Science Alliance
RING E3 ubiquitin ligases Pellino 1 and 2 are recruited to sites of DNA damage via their non-canonical FHA domains that recognise conserved phosphorylated sequence motifs in the DNA damage adaptor protein MDC1.

The STUbL RNF4 regulates protein group SUMOylation by targeting the SUMO conjugation machinery

open access: yesNature Communications, 2017
SUMO and ubiquitin are key signal transducers in several cellular processes including the DNA-damage response. Here the authors describe a method for selective enrichment of ubiquitin substrates for E3 ligases from complex cellular proteomes and identify

Cell Cycle Control of Nuclear Metabolism Couples Phosphatidylinositol Signaling to Histone Methylation

open access: yesAdvanced Science, EarlyView.
Nuclear metabolism oscillates during cell cycle progression. Quantitative chromatome proteomics and imaging reveal phase‐specific dynamics of PIP5K1A and nuclear PIP2, linking phosphatidylinositol metabolism to histone methylation. This work identifies nuclear lipid metabolism as a previously unrecognized regulatory axis coordinating chromatin ...

Development of Protacs to Target Cancer-promoting Proteins for Ubiquitination and Degradation [PDF]

open access: yes, 2003
The proteome contains hundreds of proteins that in theory could be excellent therapeutic targets for the treatment of human diseases. However, many of these proteins are from functional classes that have never been validated as viable candidates for the ...

Comparative analysis of T4 DNA ligases and DNA polymerases used in chromosome conformation capture assays

open access: yesBioTechniques, 2015
Three-dimensional (3-D) genome organization in the nuclear space affects various genomic functions. Circular chromosome conformation capture (4C-seq) is a powerful technique that allows researchers to measure long-range chromosomal interactions with a ...

Chronic Hypoxia Disrupts Spermatogenesis Through ASXL2–EZH2–Mediated Microtubule Destabilization

open access: yesAdvanced Science, EarlyView.
This study reveals the mechanism by which chronic hypoxia impairs spermatogenesis via the ASXL2–EZH2 axis, hindering the transition of spermatids from round to elongated forms. Key findings reveal that under hypoxic conditions, downregulated ASXL2 expression reduces EZH2 binding to the CEP162 promoter, leading to decreased H3K27me3 modification and ...

Arginyltransferase, Its Specificity, Putative Substrates, Bidirectional Promoter, and Splicing-derived Isoforms [PDF]

open access: yes, 2006
Substrates of the N-end rule pathway include proteins with destabilizing N-terminal residues. Three of them, Asp, Glu, and (oxidized) Cys, function through their conjugation to Arg, one of destabilizing N-terminal residues that are recognized directly by

Structure of the error-prone DNA ligase of African swine fever virus identifies critical active site residues

open access: yesNature Communications, 2019
The DNA ligase of African swine fever virus is one of the most error-prone ligases identified to date, but underlying molecular details are lacking. Here, Chen et al.
