Spd2 assists Spd1 in modulation of RNR architecture but does not regulate deoxynucleotide pools [PDF]

, 2014
In yeasts, small intrinsically disordered proteins (IDPs) modulate ribonucleotide reductase (RNR) activity to ensure an optimal supply of dNTPs for DNA synthesis. The S. pombe Spd1 protein can directly inhibit the large RNR subunit (R1), import the small

Peptide Display Directed Assembly of Biopolymer Core–Silica Shell Particles

Advanced Healthcare Materials, EarlyView.
Bacterial cells are engineered to produce biopolyester particles displaying peptides mediating growth of silica. Peptide‐coated biopolyester particles are treated with silica precursors and silica shell formation is studied. Transmission electron microscopy shows silica‐coated BPs which are formed after the silicification treatment. Characterization of

Pirh2 modulates the mitochondrial function and cytochrome c-mediated neuronal death during Alzheimer’s disease

Cell Death and Disease
Pirh2 is an E3 ubiquitin ligase known to regulate the DNA damage responses through ubiquitylation of various participating signaling factors. DNA damage is a key pathological contributor to Alzheimer’s disease (AD), therefore, the role of Pirh2 was ...

In Vitro Reconstitution Defines the Minimal Requirements for Cdc48-Dependent Disassembly of the CMG Helicase in Budding Yeast

Cell Reports, 2019
Summary: Disassembly of the replisome is the final step of chromosome duplication in eukaryotes. In budding yeast and metazoa, cullin ubiquitin ligases are required to ubiquitylate the Cdc45-MCM-GINS (CMG) helicase that lies at the heart of the replisome,

DHX36-mediated G-quadruplex unfolding is ATP-independent? [PDF]

arXiv, 2019
Chen et al. solved the crystal structure of bovine DHX36 bound to a DNA with a G-quadruplex (G4) and a single-stranded DNA segment. They believed that the mechanism they proposed may represent a general model for describing how a G4-unfolding helicase recognizes and unfolds G4 DNA.

FUS Selectively Facilitates circRNAs Packing into Small Extracellular Vesicles within Hypoxia Neuron

Advanced Science, EarlyView.
This study aimed to unravel the role of FUS in the loading of functional circRNAs into neuronal sEVs under hypoxic conditions, which involves their aggregations in SGs and specific interaction between the FUS Zf_RanBP domain to regulate circRNA sorting in sEVs.
