Targeted therapy for LIMD1-deficient non-small cell lung cancer subtypes.
(SPRINGERNATURE, 2021-11-11)An early event in lung oncogenesis is loss of the tumour suppressor gene LIMD1 (LIM domains containing 1); this encodes a scaffold protein, which suppresses tumorigenesis via a number of different mechanisms. Approximately ... -
Functional studies of genome architectural proteins CTCF and ZNF143
(Institute of Cancer Research (University Of London), 2021-09-30)The genome architecture and gene transcription are interdependent. The way chromatin is packed within the nucleus controls when and how genes are expressed. A lot of chromatin interacting proteins are involved to ensure ... -
ADP-ribosyltransferases, an update on function and nomenclature.
(WILEY, 2021-07-29)ADP-ribosylation, a modification of proteins, nucleic acids, and metabolites, confers broad functions, including roles in stress responses elicited, for example, by DNA damage and viral infection and is involved in intra- ... -
Cell cycle regulation by complex nanomachines.
(WILEY, 2021-06-18)The cell cycle is the essential biological process where one cell replicates its genome and segregates the resulting two copies into the daughter cells during mitosis. Several aspects of this process have fascinated humans ... -
Investigating the phosphinic acid tripeptide mimetic DG013A as a tool compound inhibitor of the M1-aminopeptidase ERAP1.
(PERGAMON-ELSEVIER SCIENCE LTD, 2021-06-15)ERAP1 is a zinc-dependent M1-aminopeptidase that trims lipophilic amino acids from the N-terminus of peptides. Owing to its importance in the processing of antigens and regulation of the adaptive immune response, dysregulation ... -
Large Stokes shift fluorescence activation in an RNA aptamer by intermolecular proton transfer to guanine.
(NATURE RESEARCH, 2021-06-10)Fluorogenic RNA aptamers are synthetic functional RNAs that specifically bind and activate conditional fluorophores. The Chili RNA aptamer mimics large Stokes shift fluorescent proteins and exhibits high affinity for ... -
Nse5/6 is a negative regulator of the ATPase activity of the Smc5/6 complex.
(OXFORD UNIV PRESS, 2021-05-07)The multi-component Smc5/6 complex plays a critical role in the resolution of recombination intermediates formed during mitosis and meiosis, and in the cellular response to replication stress. Using recombinant proteins, ... -
Architecture of the chromatin remodeler RSC and insights into its nucleosome engagement.
(ELIFE SCIENCES PUBLICATIONS LTD, 2019-12-30)Eukaryotic DNA is packaged into nucleosome arrays, which are repositioned by chromatin remodeling complexes to control DNA accessibility. The Saccharomyces cerevisiae RSC (Remodeling the Structure of Chromatin) complex, a ... -
A commercial antibody to the human condensin II subunit NCAPH2 cross-reacts with a SWI/SNF complex component.
(F1000 Research Ltd, 2021-01-13)Condensin complexes compact and disentangle chromosomes in preparation for cell division. Commercially available antibodies raised against condensin subunits have been widely used to characterise their cellular interactome. ... -

Structure of human RNA polymerase III.
(NATURE RESEARCH, 2020-12-17)In eukaryotes, RNA Polymerase (Pol) III is specialized for the transcription of tRNAs and other short, untranslated RNAs. Pol III is a determinant of cellular growth and lifespan across eukaryotes. Upregulation of Pol III ... -
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, ... -
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 ... -
Origin licensing requires ATP binding and hydrolysis by the MCM replicative helicase.
(CELL PRESS, 2014-09-04)Loading of the six related Minichromosome Maintenance (MCM) proteins as head-to-head double hexamers during DNA replication origin licensing is crucial for ensuring once-per-cell-cycle DNA replication in eukaryotic cells. ... -
RET recognition of GDNF-GFRα1 ligand by a composite binding site promotes membrane-proximal self-association.
(CELL PRESS, 2014-09-25)The RET receptor tyrosine kinase is essential to vertebrate development and implicated in multiple human diseases. RET binds a cell surface bipartite ligand comprising a GDNF family ligand and a GFRα coreceptor, resulting ... -
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 ... -
SF3B1 mutations constitute a novel therapeutic target in breast cancer.
(WILEY, 2015-03-01)Mutations in genes encoding proteins involved in RNA splicing have been found to occur at relatively high frequencies in several tumour types including myelodysplastic syndromes, chronic lymphocytic leukaemia, uveal melanoma, ... -
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 ... -
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 ...
