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, ...
A high-content RNAi screen reveals multiple roles for long noncoding RNAs in cell division.
(NATURE PUBLISHING GROUP, 2020-04-15)
Genome stability relies on proper coordination of mitosis and cytokinesis, where dynamic microtubules capture and faithfully segregate chromosomes into daughter cells. With a high-content RNAi imaging screen targeting more ...
Conditional control of fluorescent protein degradation by an auxin-dependent nanobody.
(NATURE PUBLISHING GROUP, 2018-08-17)
The conditional and reversible depletion of proteins by auxin-mediated degradation is a powerful tool to investigate protein functions in cells and whole organisms. However, its wider applications require fusing the ...
PLK1 Activation in Late G2 Sets Up Commitment to Mitosis.
(CELL PRESS, 2017-06-06)
Commitment to mitosis must be tightly coordinated with DNA replication to preserve genome integrity. While we have previously established that the timely activation of CyclinB1-Cdk1 in late G2 triggers mitotic entry, the ...
Degron-tagged reporters probe membrane topology and enable the specific labelling of membrane-wrapped structures.
(NATURE PUBLISHING GROUP, 2019-08-02)
Visualization of specific organelles in tissues over background fluorescence can be challenging, especially when reporters localize to multiple structures. Instead of trying to identify proteins enriched in specific ...
EXD2 Protects Stressed Replication Forks and Is Required for Cell Viability in the Absence of BRCA1/2.
(CELL PRESS, 2019-08-08)
Accurate DNA replication is essential to preserve genomic integrity and prevent chromosomal instability-associated diseases including cancer. Key to this process is the cells' ability to stabilize and restart stalled ...
The midbody interactome reveals unexpected roles for PP1 phosphatases in cytokinesis.
(NATURE PUBLISHING GROUP, 2019-10-04)
The midbody is an organelle assembled at the intercellular bridge between the two daughter cells at the end of mitosis. It controls the final separation of the daughter cells and has been involved in cell fate, polarity, ...
Requirement for PBAF in transcriptional repression and repair at DNA breaks in actively transcribed regions of chromatin.
(CELL PRESS, 2014-09-04)
Actively transcribed regions of the genome are vulnerable to genomic instability. Recently, it was discovered that transcription is repressed in response to neighboring DNA double-strand breaks (DSBs). It is not known ...
Removal of H2A.Z by INO80 promotes homologous recombination.
(WILEY, 2015-08-01)
The mammalian INO80 remodelling complex facilitates homologous recombination (HR), but the mechanism by which it does this is unclear. Budding yeast INO80 can remove H2A.Z/H2B dimers from chromatin and replace them with ...
