Structural basis for antiepileptic drugs and botulinum neurotoxin recognition of SV2A

Nature Communications
More than one percent of people have epilepsy worldwide. Levetiracetam (LEV) is a successful new-generation antiepileptic drug (AED), and its derivative, brivaracetam (BRV), shows improved efficacy.

Protein folding and models of dynamics on the lattice

, 1998
We study folding in 16-monomer heteropolymers on the square lattice. For a given sequence, thermodynamic properties and stability of the native state are unique.

Structural basis for DNA damage-induced phosphoregulation of MDM2 RING domain

Nature Communications, 2020
p53 is an important tumor suppressor protein which is regulated by the E3 ubiquitin ligase MDM2. Here the authors reveal that DNA damage-induced Ser429 phosphorylation of MDM2 serve to boost the activity of MDM2 homodimer by stabilizing the active E2 ...

Simulations of Higher-Order Protein Organizations Using a Fuzzy Framework

Complexity, 2018
Spatiotemporal regulation of the biochemical information is often linked to supramolecular organizations proteins and nucleic acids, the driving forces of which have yet to be elucidated. Although the critical role of multivalency in phase transition has

A dual fluorescent-Raman bioorthogonal probe for specific biosynthetic labeling of intracellular gangliosides

Communications Chemistry
Gangliosides are sialic acid-containing glycosphingolipids integral to the cell membrane, and they are particularly abundant in the nervous system.

MPS1 promotes timely spindle bipolarization to prevent kinetochore-microtubule attachment errors in oocytes

The EMBO Journal
Incorrect kinetochore–microtubule attachment leads to chromosome segregation errors. The risk of incorrect attachment is high in acentrosomal oocytes, where kinetochores are surrounded by randomly oriented microtubules until spindle bipolarization ...

Defining essential charged residues in fibril formation of a lysosomal derived N-terminal α-synuclein truncation

Nature Communications
N- and C-terminal α-synuclein (α-syn) truncations are prevalent in Parkinson’s disease. Effects of the N- and C-terminal residues on α-syn aggregation and fibril propagation are distinct, where the N-terminus dictates fibril structure. Here, the majority

Simultaneous in vitro expression of minimal 21 transfer RNAs by tRNA array method

Nature Communications
Transfer RNA (tRNA) plays a central role in translation. The simultaneous in vitro synthesis of minimal yet sufficient tRNA species (at least 21) poses a challenge for constructing a self-reproducible artificial cell.

A cyclic peptide-grafted Fc with hepatocyte growth factor functionality ameliorates hepatic fibrosis in a non-alcoholic steatohepatitis mouse model

iScience
Summary: The regenerative functions associated with cytokines and growth factors have immense therapeutic potential; however, their poor pharmacokinetics, resulting from structural features, hinder their effectiveness.

Efficiency of transcription and translation of cell-free protein synthesis systems in cell-sized lipid vesicles with changing lipid composition determined by fluorescence measurements

Scientific Reports
To develop artificial cell models that mimic living cells, cell-sized lipid vesicles encapsulating cell-free protein synthesis (CFPS) systems are useful for protein expressions or artificial gene circuits for vesicle–vesicle communications.
