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 ...
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 ...
DNA origami-based single-molecule force spectroscopy elucidates RNA Polymerase III pre-initiation complex stability.
(NATURE PUBLISHING GROUP, 2020-06-05)
The TATA-binding protein (TBP) and a transcription factor (TF) IIB-like factor are important constituents of all eukaryotic initiation complexes. The reason for the emergence and strict requirement of the additional ...
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 ...
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. ...
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- ...
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 ...
Structural basis of intron selection by U2 snRNP in the presence of covalent inhibitors
(Springer Science and Business Media LLC, 2021-07-23)
<jats:title>Abstract</jats:title><jats:p>Intron selection during the formation of prespliceosomes is a critical event in pre-mRNA splicing. Chemical modulation of intron selection has emerged as a route for cancer therapy. ...
Molecular basis for the bifunctional Uba4-Urm1 sulfur-relay system in tRNA thiolation and ubiquitin-like conjugation.
(WILEY, 2020-10-01)
The chemical modification of tRNA bases by sulfur is crucial to tune translation and to optimize protein synthesis. In eukaryotes, the ubiquitin-related modifier 1 (Urm1) pathway is responsible for the synthesis of 2-thiolated ...
