GenomicsPromoters Active in Interphase are Bookmarked during Mitosis by Ubiquitination
We analyzed genome-wide modification of chromatin by ubiquitination in human cells and whether this mark changes through the cell cycle using modified ChIP-seq technique (ChAP-seq). Chromatin affinity purification was based on a standard ChIP method with modification of a two-step affinity purificat...

ProteomicsCalcium-triggered (de)ubiquitination events in synapses
Neuronal communication relies on neurotransmitter release from synaptic vesicles (SVs), whose dynamics are controlled by Ca2+-dependent pathways, as many thoroughly studied phosphorylation cascades. However, little is known about other post-translational modifications, as ubiquitination. To address ...

GenomicsThe Mediator complex subunit MED23 couples H2B mono-ubiquitination to transcriptional control and cell fate determination
The Mediator complex orchestrates multiple transcription factors with the Pol II apparatus for precise transcriptional control. However, its interplay with the surrounding chromatin remains poorly understood. Here, we analyze differential histone modifications between WT and MED23-/- (KO) cells and ...

ProteomicsThe identification of ubiquitination sites of IBTK by shotgun proteomics
Previous study reported that eIF4A1 protein stability is subject to control by the ubiquitin-proteasome pathway, and deubiquitinase USP9X elevated eIF4A1 protein level by promoting eIF4A1 deubiquitination. However, the E3 ubiquitin ligases responsible for eIF4A1 proteolysis is not determined. Our re...

ProteomicsSelective ubiquitination of drug-like small molecules by the ubiquitin ligase HUWE1
The ubiquitin system regulates myriad pathways in eukaryotic physiology by modifying specific substrate proteins. The recognition of the substrates and the assembly of ubiquitin signals on them – key specificity determinants in ubiquitin signaling - are determined by the diversified class of ubiquit...

ProteomicsSelective ubiquitination of drug-like small molecules by the ubiquitin ligase HUWE1
The ubiquitin system regulates eukaryotic physiology by modifying specific substrate proteins. Substrate recruitment and the assembly of ubiquitin signals are determined by ubiquitin ligases, some of which also modify non-protein biomolecules. Here we expand this substrate realm, revealing that the ...

ProteomicsUbiquitination at the Parkin ubiquitin-like domain suggests a new mechanism for Parkin activation
The mitochondrial kinase PINK1 and the cytosolic ubiquitin ligase (E3) Parkin is involved in mitochondrial quality control. PINK1, which phosphorylates ubiquitin at serine 65 residue and the ubiquitin-like (Ubl) domain of Parkin at serine 65 residue, promotes the Parkin activation and translocation ...

TranscriptomicsStress-dependent CHIP/Daxx interaction suppresses the p53 apoptotic program
Our previous studies have implicated CHIP as a co-chaperone/ubiquitin ligase, whose activities yield protection against stress-induced apoptotic events. In this report, we demonstrate a stress-dependent interaction between CHIP (carboxyl terminus of Hsp70-interacting protein) and Daxx, death domain-...
