Viscosity-Dependent Protein Dynamics [PDF]

open access: yesBiophysical Journal, 2007
Spectrally resolved stimulated vibrational echo spectroscopy is used to investigate the dependence of fast protein dynamics on bulk solution viscosity at room temperature in four heme proteins: hemoglobin, myoglobin, a myoglobin mutant with the distal histidine replaced by a valine (H64V), and a cytochrome c552 mutant with the distal methionine ...

Towards a Stochastic Paradigm: From Fuzzy Ensembles to Cellular Functions

open access: yesMolecules, 2018
The deterministic sequence → structure → function relationship is not applicable to describe how proteins dynamically adapt to different cellular conditions. A stochastic model is required to capture functional promiscuity, redundant sequence

Cytosolic calcium regulates cytoplasmic accumulation of TDP-43 through Calpain-A and Importin α3

open access: yeseLife, 2020
Cytoplasmic accumulation of TDP-43 in motor neurons is the most prominent pathological feature in amyotrophic lateral sclerosis (ALS). A feedback cycle between nucleocytoplasmic transport (NCT) defect and TDP-43 aggregation was shown to contribute to ...

Identification of TCR repertoires in functionally competent cytotoxic T cells cross-reactive to SARS-CoV-2

open access: yesCommunications Biology, 2021
Kanako Shimizu et al. identify HLA-A24 high-binding epitopes in the SARS-CoV-2 spike region and investigate their cross-reactivity with CD8+ T cell receptors.

Structural basis of Gip1 for cytosolic sequestration of G protein in wide-range chemotaxis

open access: yesNature Communications, 2018
Gip1 sequesters heterotrimeric G proteins in the cytosolic pool which regulates G protein-coupled receptor signalling for eukaryotic chemotaxis. Here the authors provide the crystal structure of Gip1's G protein-binding region and show that mutations in ...

A topological approach for protein classification

open access: yes, 2015
Protein function and dynamics are closely related to its sequence and structure. However prediction of protein function and dynamics from its sequence and structure is still a fundamental challenge in molecular biology.

Identifying the protein folding nucleus using molecular dynamics [PDF]

open access: yes, 2000
Molecular dynamics simulations of folding in an off-lattice protein model reveal a nucleation scenario, in which a few well-defined contacts are formed with high probability in the transition state ensemble of conformations.

Evidence of a low-temperature dynamical transition in concentrated microgels [PDF]

open access: yes, 2018
A low-temperature dynamical transition has been reported in several proteins. We provide the first observation of a `protein-like' dynamical transition in nonbiological aqueous environments.

Mapping the molecular and structural specialization of the skin basement membrane for inter-tissue interactions

open access: yesNature Communications, 2021
The basement membrane is located at tissue interfaces, but how it mediates distinct inter-tissue interactions is unclear. Here, the authors systematically define the spatial heterogeneity of skin basement membrane composition and show its functional ...
