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 ...

TranscriptomicsExpression data from 17 day old testes of wild type and UBR2-/- mice
Ubiquitylation of histones provides an important mechanism regulating chromatin remodeling and gene expression. Recent studies have revealed ubiquitin ligases involved in histone ubiquitylation, yet the responsible enzymes and the function of histone ubiquitination in spermatogenesis remain unclear....

ProteomicsAn impaired respiratory electron chain triggers down-regulation of the energy metabolism and de-ubiquitination of solute carrier amino acid transporters
We integrated metabolome and proteome profiles of the parental cell line 143B.TK- versus ?0, including PTM analyses such as phosphorylation and ubiquitination to characterize the impact of the absence of mtDNA for the entire cell. For quantitative proteome profiling, we used a shotgun LC-MS/MS appro...

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...

GenomicsChIP-seq analysis of PHF20 and Wdr5 binding sites in ESCs
Although reprogramming of somatic cells to generate inducible pluripotent stem cells (iPSCs) is associated with remarkable epigenetic changes, the role and mechanisms of epigenetic factors in this process remains poorly understood. Here we describe identification of Jmjd3 as a potent negative regula...

TranscriptomicsThe Role of the Rad4-Rad23 Complex and Rad4 Ubiquitination in UV-Responsive Transcription
The Rad23/Rad4 protein complex plays a major role in DNA damage recognition during nucleotide excision repair (NER) in yeast. We recently showed that two distinct pathways contribute to efficient NER in yeast. The first operates independently of de novo protein synthesis and requires a nonproteolyti...

TranscriptomicsPRC1.6 molecule L3MBTL2 protects MYCN-amplified neuroblastoma cells via epigenetic gene suppression
Polycomb-group complexes are evolutionarily conserved epigenetic machineries that regulate stem cell fate decisions/development and are also implicated in tumorigenesis mainly by histone modification. PRC1 complexes mediates ubiquitylation of histone H2A on lysine 119 and consists of PRC1.1 to PRC1....

TranscriptomicsPost-transcriptional fine-tuning of COP9 signalosome subunit biosynthesis is regulated by the c-Myc/Lin28B/let-7 pathway
The COP9 signalosome (CSN) is a conserved protein complex occurring in all eukaryotes. The mammalian CSN consists of eight subunits (CSN1 – CSN8) and possesses an intrinsic metalloprotease JAMM motif localised to CSN5. In addition, it is associated with kinases such as protein kinase CK2 and D and t...
