Relaxed and active thin filament structures; a new structural basis for the regulatory mechanism.
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2017-03-01)The structures of muscle thin filaments reconstituted using skeletal actin and cardiac troponin and tropomyosin have been determined with and without bound Ca2+ using electron microscopy and reference-free single particle ... -
Characterization of Hedgehog Acyltransferase Inhibitors Identifies a Small Molecule Probe for Hedgehog Signaling by Cancer Cells.
(AMER CHEMICAL SOC, 2016-12-16)The Sonic Hedgehog (Shh) signaling pathway plays a critical role during embryonic development and cancer progression. N-terminal palmitoylation of Shh by Hedgehog acyltransferase (Hhat) is essential for efficient signaling, ... -
Discovery of a Chemical Probe Bisamide (CCT251236): An Orally Bioavailable Efficacious Pirin Ligand from a Heat Shock Transcription Factor 1 (HSF1) Phenotypic Screen.
(AMER CHEMICAL SOC, 2017-01-12)Phenotypic screens, which focus on measuring and quantifying discrete cellular changes rather than affinity for individual recombinant proteins, have recently attracted renewed interest as an efficient strategy for drug ... -
Inhibition of mTOR-kinase destabilizes MYCN and is a potential therapy for MYCN-dependent tumors.
(IMPACT JOURNALS LLC, 2016-09-06)MYC oncoproteins deliver a potent oncogenic stimulus in several human cancers, making them major targets for drug development, but efforts to deliver clinically practical therapeutics have not yet been realized. In childhood ... -
AXIN Shapes Tankyrase ARChitecture.
(CELL PRESS, 2016-10-04)The poly(ADP-ribose)polymerase (PARP) Tankyrase uses ankyrin repeat modules to capture substrates via Tankyrase-binding peptide motifs. In this issue of Structure, Eisemann et al. (2016) describe how the signaling protein ... -
Exploiting Protein Conformational Change to Optimize Adenosine-Derived Inhibitors of HSP70.
(AMER CHEMICAL SOC, 2016-05-26)HSP70 is a molecular chaperone and a key component of the heat-shock response. Because of its proposed importance in oncology, this protein has become a popular target for drug discovery, efforts which have as yet brought ... -
Nanostructures from Synthetic Genetic Polymers.
(WILEY-V C H VERLAG GMBH, 2016-06-16)Nanoscale objects of increasing complexity can be constructed from DNA or RNA. However, the scope of potential applications could be enhanced by expanding beyond the moderate chemical diversity of natural nucleic acids. ... -
Rapid Discovery of Pyrido[3,4-d]pyrimidine Inhibitors of Monopolar Spindle Kinase 1 (MPS1) Using a Structure-Based Hybridization Approach.
(AMER CHEMICAL SOC, 2016-04-28)Monopolar spindle 1 (MPS1) plays a central role in the transition of cells from metaphase to anaphase and is one of the main components of the spindle assembly checkpoint. Chromosomally unstable cancer cells rely heavily ... -
Synthesis of a Ribose-Incorporating Medium Ring Scaffold via a Challenging Ring-Closing Metathesis Reaction.
(WILEY-V C H VERLAG GMBH, 2016-09-01)A practical synthesis of a novel oxabicyclo[6.2.1]undecenetriol useful as a medicinal chemistry scaffold has been developed starting from l-ribose. The sequence involves an oxidation/Grignard addition sequence and a ... -
2,8-Disubstituted-1,6-Naphthyridines and 4,6-Disubstituted-Isoquinolines with Potent, Selective Affinity for CDK8/19.
(AMER CHEMICAL SOC, 2016-06-09)We demonstrate a designed scaffold-hop approach to the discovery of 2,8-disubstituted-1,6-naphthyridine- and 4,6-disubstituted-isoquinoline-based dual CDK8/19 ligands. Optimized compounds in both series exhibited rapid ... -
REVEL: An Ensemble Method for Predicting the Pathogenicity of Rare Missense Variants.
(CELL PRESS, 2016-10-06)The vast majority of coding variants are rare, and assessment of the contribution of rare variants to complex traits is hampered by low statistical power and limited functional data. Improved methods for predicting the ... -
Redox Signaling by the RNA Polymerase III TFIIB-Related Factor Brf2.
(CELL PRESS, 2015-12-03)TFIIB-related factor 2 (Brf2) is a member of the family of TFIIB-like core transcription factors. Brf2 recruits RNA polymerase (Pol) III to type III gene-external promoters, including the U6 spliceosomal RNA and selenocysteine ... -
A closed conformation of the Caenorhabditis elegans separase-securin complex.
(ROYAL SOC, 2016-04-13)The protease separase plays a key role in sister chromatid disjunction and centriole disengagement. To maintain genomic stability, separase activity is strictly regulated by binding of an inhibitory protein, securin. Despite ... -
A fragment-based approach applied to a highly flexible target: Insights and challenges towards the inhibition of HSP70 isoforms.
(NATURE PORTFOLIO, 2016-10-06)The heat shock protein 70s (HSP70s) are molecular chaperones implicated in many cancers and of significant interest as targets for novel cancer therapies. Several HSP70 inhibitors have been reported, but because the majority ... -
Tankyrase Requires SAM Domain-Dependent Polymerization to Support Wnt-β-Catenin Signaling.
(CELL PRESS, 2016-08-04)The poly(ADP-ribose) polymerase (PARP) Tankyrase (TNKS and TNKS2) is paramount to Wnt-β-catenin signaling and a promising therapeutic target in Wnt-dependent cancers. The pool of active β-catenin is normally limited by ... -
