Prereplicative complexes assembled in vitro support origin-dependent and independent DNA replication.
(WILEY-BLACKWELL, 2014-03-18)
Eukaryotic DNA replication initiates from multiple replication origins. To ensure each origin fires just once per cell cycle, initiation is divided into two biochemically discrete steps: the Mcm2-7 helicase is first loaded ...
Binding to an Unusual Inactive Kinase Conformation by Highly Selective Inhibitors of Inositol-Requiring Enzyme 1α Kinase-Endoribonuclease.
(AMER CHEMICAL SOC, 2019-02-19)
A series of imidazo[1,2- b]pyridazin-8-amine kinase inhibitors were discovered to allosterically inhibit the endoribonuclease function of the dual kinase-endoribonuclease inositol-requiring enzyme 1α (IRE1α), a key component ...
High Proliferation Rate and a Compromised Spindle Assembly Checkpoint Confers Sensitivity to the MPS1 Inhibitor BOS172722 in Triple-Negative Breast Cancers.
(AMER ASSOC CANCER RESEARCH, 2019-10-01)
BOS172722 (CCT289346) is a highly potent, selective, and orally bioavailable inhibitor of spindle assembly checkpoint kinase MPS1. BOS172722 treatment alone induces significant sensitization to death, particularly in highly ...
Cnn1 inhibits the interactions between the KMN complexes of the yeast kinetochore.
(NATURE PUBLISHING GROUP, 2012-05-06)
Kinetochores attach the replicated chromosomes to the mitotic spindle and orchestrate their transmission to the daughter cells. Kinetochore-spindle binding and chromosome segregation are mediated by the multi-copy KNL1(Spc105), ...
Characterisation of CCT271850, a selective, oral and potent MPS1 inhibitor, used to directly measure in vivo MPS1 inhibition vs therapeutic efficacy.
(NATURE PUBLISHING GROUP, 2017-04-25)
BACKGROUND: The main role of the cell cycle is to enable error-free DNA replication, chromosome segregation and cytokinesis. One of the best characterised checkpoint pathways is the spindle assembly checkpoint, which ...
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 ...
Regulation of Protein Interactions by Mps One Binder (MOB1) Phosphorylation.
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2017-06-01)
MOB1 is a multifunctional protein best characterized for its integrative role in regulating Hippo and NDR pathway signaling in metazoans and the Mitotic Exit Network in yeast. Human MOB1 binds both the upstream kinases ...
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 ...
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 ...
Molecular basis of APC/C regulation by the spindle assembly checkpoint.
(NATURE PUBLISHING GROUP, 2016-08-25)
In the dividing eukaryotic cell, the spindle assembly checkpoint (SAC) ensures that each daughter cell inherits an identical set of chromosomes. The SAC coordinates the correct attachment of sister chromatid kinetochores ...
