Discovery of Potent, Selective, and Orally Bioavailable Small-Molecule Modulators of the Mediator Complex-Associated Kinases CDK8 and CDK19.
(AMER CHEMICAL SOC, 2016-02-11)
The Mediator complex-associated cyclin-dependent kinase CDK8 has been implicated in human disease, particularly in colorectal cancer where it has been reported as a putative oncogene. Here we report the discovery of 109 ...
Human Condensin I and II Drive Extensive ATP-Dependent Compaction of Nucleosome-Bound DNA.
(CELL PRESS, 2020-07-02)
Structural maintenance of chromosomes (SMC) complexes are essential for genome organization from bacteria to humans, but their mechanisms of action remain poorly understood. Here, we characterize human SMC complexes condensin ...
Structural basis of RNA polymerase III transcription initiation.
(NATURE PORTFOLIO, 2018-01-17)
RNA polymerase (Pol) III transcribes essential non-coding RNAs, including the entire pool of transfer RNAs, the 5S ribosomal RNA and the U6 spliceosomal RNA, and is often deregulated in cancer cells. The initiation of gene ...
RavN is a member of a previously unrecognized group of Legionella pneumophila E3 ubiquitin ligases.
(PUBLIC LIBRARY SCIENCE, 2018-02-01)
The eukaryotic ubiquitylation machinery catalyzes the covalent attachment of the small protein modifier ubiquitin to cellular target proteins in order to alter their fate. Microbial pathogens exploit this post-translational ...
Cryo-EM structures of the XPF-ERCC1 endonuclease reveal how DNA-junction engagement disrupts an auto-inhibited conformation.
(NATURE PUBLISHING GROUP, 2020-02-28)
The structure-specific endonuclease XPF-ERCC1 participates in multiple DNA damage repair pathways including nucleotide excision repair (NER) and inter-strand crosslink repair (ICLR). How XPF-ERCC1 is catalytically activated ...
Mechanism for remodelling of the cell cycle checkpoint protein MAD2 by the ATPase TRIP13.
(NATURE PUBLISHING GROUP, 2018-07-12)
The maintenance of genome stability during mitosis is coordinated by the spindle assembly checkpoint (SAC) through its effector the mitotic checkpoint complex (MCC), an inhibitor of the anaphase-promoting complex (APC/C, ...
Structural Basis for Auto-Inhibition of the NDR1 Kinase Domain by an Atypically Long Activation Segment.
(CELL PRESS, 2018-08-07)
The human NDR family kinases control diverse aspects of cell growth, and are regulated through phosphorylation and association with scaffolds such as MOB1. Here, we report the crystal structure of the human NDR1 kinase ...
Demonstrating In-Cell Target Engagement Using a Pirin Protein Degradation Probe (CCT367766).
(AMER CHEMICAL SOC, 2018-02-08)
Demonstrating intracellular protein target engagement is an essential step in the development and progression of new chemical probes and potential small molecule therapeutics. However, this can be particularly challenging ...
The discovery of potent ribosomal S6 kinase inhibitors by high-throughput screening and structure-guided drug design.
(IMPACT JOURNALS LLC, 2013-08-25)
The ribosomal P70 S6 kinases play a crucial role in PI3K/mTOR regulated signalling pathways and are therefore potential targets for the treatment of a variety of diseases including diabetes and cancer. In this study we ...
Molecular mechanisms of human IRE1 activation through dimerization and ligand binding.
(IMPACT JOURNALS LLC, 2015-05-30)
IRE1 transduces the unfolded protein response by splicing XBP1 through its C-terminal cytoplasmic kinase-RNase region. IRE1 autophosphorylation is coupled to RNase activity through formation of a back-to-back dimer, although ...
