An E2-ubiquitin thioester-driven approach to identify substrates modified with ubiquitin and ubiquitin-like molecules.
(NATURE PUBLISHING GROUP, 2018-11-14)
Covalent modifications of proteins with ubiquitin and ubiquitin-like molecules are instrumental to many biological processes. However, identifying the E3 ligase responsible for these modifications remains a major bottleneck ...
Autoinhibition Mechanism of the Ubiquitin-Conjugating Enzyme UBE2S by Autoubiquitination.
(CELL PRESS, 2019-08-06)
Ubiquitin-conjugating enzymes (E2s) govern key aspects of ubiquitin signaling. Emerging evidence suggests that the activities of E2s are modulated by posttranslational modifications; the structural underpinnings, however, ...
Genomic Determinants of Protein Abundance Variation in Colorectal Cancer Cells.
(CELL PRESS, 2017-08-29)
Assessing the impact of genomic alterations on protein networks is fundamental in identifying the mechanisms that shape cancer heterogeneity. We have used isobaric labeling to characterize the proteomic landscapes of 50 ...
Proteomic characterisation of triple negative breast cancer cells following CDK4/6 inhibition.
(NATURE PORTFOLIO, 2022-07-11)
When used in combination with hormone treatment, Palbociclib prolongs progression-free survival of patients with hormone receptor positive breast cancer. Mechanistically, Palbociclib inhibits CDK4/6 activity but the basis ...
Mechanism of assembly, activation and lysine selection by the SIN3B histone deacetylase complex.
(NATURE PORTFOLIO, 2023-05-03)
Lysine acetylation in histone tails is a key post-translational modification that controls transcription activation. Histone deacetylase complexes remove histone acetylation, thereby repressing transcription and regulating ...
SimPLIT: Simplified Sample Preparation for Large-Scale Isobaric Tagging Proteomics.
(AMER CHEMICAL SOC, 2022-08-05)
Large scale proteomic profiling of cell lines can reveal molecular signatures attributed to variable genotypes or induced perturbations, enabling proteogenomic associations and elucidation of pharmacological mechanisms of ...
Integrative epigenomics, transcriptomics and proteomics of patient chondrocytes reveal genes and pathways involved in osteoarthritis.
(NATURE PORTFOLIO, 2017-08-21)
Osteoarthritis (OA) is a common disease characterized by cartilage degeneration and joint remodeling. The underlying molecular changes underpinning disease progression are incompletely understood. We investigated genes and ...
Aneuploidy tolerance caused by BRG1 loss allows chromosome gains and recovery of fitness.
(NATURE PORTFOLIO, 2022-04-01)
Aneuploidy results in decreased cellular fitness in many species and model systems. However, aneuploidy is commonly found in cancer cells and often correlates with aggressive growth, suggesting that the impact of aneuploidy ...
Citrobacter rodentium Subverts ATP Flux and Cholesterol Homeostasis in Intestinal Epithelial Cells In Vivo.
(CELL PRESS, 2017-11-07)
The intestinal epithelial cells (IECs) that line the gut form a robust line of defense against ingested pathogens. We investigated the impact of infection with the enteric pathogen Citrobacter rodentium on mouse IEC ...
Interferon-driven alterations of the host's amino acid metabolism in the pathogenesis of typhoid fever.
(ROCKEFELLER UNIV PRESS, 2016-05-30)
Enteric fever, caused by Salmonella enterica serovar Typhi, is an important public health problem in resource-limited settings and, despite decades of research, human responses to the infection are poorly understood. In ...
