Achieving In Vivo Target Depletion through the Discovery and Optimization of Benzimidazolone BCL6 Degraders.
(AMER CHEMICAL SOC, 2020-04-23)Deregulation of the transcriptional repressor BCL6 enables tumorigenesis of germinal center B-cells, and hence BCL6 has been proposed as a therapeutic target for the treatment of diffuse large B-cell lymphoma (DLBCL). ... -
A unique binding mode of Nek2A to the APC/C allows its ubiquitination during prometaphase.
(WILEY, 2020-06-04)The anaphase-promoting complex (APC/C) is the key E3 ubiquitin ligase which directs mitotic progression and exit by catalysing the sequential ubiquitination of specific substrates. The activity of the APC/C in mitosis is ... -
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 ... -
Alternative catalytic residues in the active site of Esco acetyltransferases.
(NATURE PORTFOLIO, 2020-06-17)Cohesin is a protein complex whose core subunits, Smc1, Smc3, Scc1, and SA1/SA2 form a ring-like structure encircling the DNA. Cohesins play a key role in the expression, repair, and segregation of eukaryotic genomes. ... -
Hybrid Gene Origination Creates Human-Virus Chimeric Proteins during Infection.
(CELL PRESS, 2020-06-25)RNA viruses are a major human health threat. The life cycles of many highly pathogenic RNA viruses like influenza A virus (IAV) and Lassa virus depends on host mRNA, because viral polymerases cleave 5'-m7G-capped host ... -
Human Condensin I and II Drive Extensive ATP-Dependent Compaction of Nucleosome-Bound DNA.
(CELL PRESS, 2020-07-02)Structural maintenance of chromosomes (SMC) complexes are essential for genome organization from bacteria to humans, but their mechanisms of action remain poorly understood. Here, we characterize human SMC complexes condensin ... -
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 ... -
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 ... -
A commercial antibody to the human condensin II subunit NCAPH2 cross-reacts with a SWI/SNF complex component
(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. ... -

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, ... -
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 ... -
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 ... -
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 ... -
