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 ...
Molecular mechanism of APC/C activation by mitotic phosphorylation.
(NATURE PUBLISHING GROUP, 2016-05-12)
In eukaryotes, the anaphase-promoting complex (APC/C, also known as the cyclosome) regulates the ubiquitin-dependent proteolysis of specific cell-cycle proteins to coordinate chromosome segregation in mitosis and entry ...
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 ...
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 ...
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), ...
Reconstitution of the destruction complex defines roles of AXIN polymers and APC in β-catenin capture, phosphorylation, and ubiquitylation.
(CELL PRESS, 2021-08-19)
The Wnt/β-catenin pathway is a highly conserved, frequently mutated developmental and cancer pathway. Its output is defined mainly by β-catenin's phosphorylation- and ubiquitylation-dependent proteasomal degradation, ...
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 ...
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 ...
MOB1 Mediated Phospho-recognition in the Core Mammalian Hippo Pathway.
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2017-06-01)
The Hippo tumor suppressor pathway regulates organ size and tissue homoeostasis in response to diverse signaling inputs. The core of the pathway consists of a short kinase cascade: MST1 and MST2 phosphorylate and activate ...
