MetabolomicsA new perspective on semen quality of aged male: The characteristics of metabolomics and proteomics

BACKGROUND: Semen quality is negatively correlated with male age and is mainly quantified by a routine semen analysis, which is descriptive and inconclusive. Sperm proteins or semen metabolites are used as the intermediate or end-products, reflecting changes in semen quality, an...

ProteomicsProteome analysis of i-motif DNA binding proteins
Non-canonical DNA structures such as G-quadruplex (G4) and i-motif (iM) are formed at the guanine- and cytosine-rich sequences, respectively, and prohibit DNA replication and transcription. The formation and resolution of these non-canonical structures are therefore required to be dynamically regula...

ProteomicsDNA binding reorganizes the intrinsically disordered C-terminal region of PSC in Drosophila PRC1
Polycomb Group (PcG) proteins regulate gene expression by modifying chromatin. A key PcG complex, PRC1, has two activities: a ubiquitin ligase activity for histone H2A, and a chromatin compacting/nucleosome bridging activity that can inhibit transcription and chromatin remodeling. In Drosophila, the...

ProteomicsNucleosome binding by the pioneer transcription factor OCT4
The nucleosome is a fundamental unit of chromatin in eukaryotes, and generally prevents the binding of transcription factors to genomic DNA. Pioneer transcription factors overcome the nucleosome barrier, and bind their target DNA sequences in chromatin. OCT4 is a representative pioneer transcription...

ProteomicsMudPIT analysis of proteins extracted from mouse KH2ES cell nuclei and enriched by binding to immobilized DNA fragments
Sample Preparation: To identify proteins that are recruited by Hoxb1 to two newly identified DNA motifs, namely Motif_2 and LONG2x, nuclear extracts from 24hrs Retinoic acid- and Doxycycline-induced KH2 cell line with inducible Hoxb1 were added to DNA fragments immobilized on magnetic beads. Five ex...

TranscriptomicsTranscription factor cooperativity in early adipogenic hotspots and super-enhancers
Here we have used a combination of advanced proteomics and genomics approaches to investigate the extent and mechanisms of transcription factor cross-talk at genomic hotspots. We identify ~12,000 transcription factor hotspots in the early phase of adipogenesis, and we find evidence of both simultane...

ProteomicsStructural proteomics based investigation of DNA binding domain (DBD) of FOXO4 transcription factor in complex with DNA binding element (DNA)
The limited information available on the structure of complexes involving transcription factors and cognate DNA response elements represents a major obstacle in the quest to understand their mechanism of action at the molecular level. We implemented a concerted structural proteomics approach, which ...

ProteomicsDepletion of the RNA binding protein HNRNPD impairs homologous recombination by inhibiting DNA-end resection and inducing R-loop accumulation
DNA double strand break (DSB) repair through homologous recombination (HR) is crucial to maintain genome stability. DSB resection generates a single strand DNA intermediate, which is crucial for the HR process. We used a synthetic DNA structure, mimicking a resection intermediate, as a bait to ident...

ProteomicsGlobal profiling of protein-DNA and protein-nucleosome binding affinities using quantitative mass spectrometry
Interaction proteomics studies have provided fundamental insights into multimeric biomolecular assemblies and cell-scale molecular networks. Significant recent developments in mass spectrometry-based interaction proteomics have been fueled by rapid advances in label-free, isotopic, and isobaric quan...

ProteomicsMetalloprotease SPRTN/DVC1 Orchestrates Replication-Coupled DNA-Protein Crosslink Removal
Cytotoxicity of DNA-protein crosslinks (DPCs) is ascribed largely to their ability to block the progression of DNA replication fork. DPCs are frequently occurring in cells, either as a consequence of metabolism or exogenous agents. The mechanism of DPCs removal is not completely understood. Here, we...
