Efficient sampling of large-scale transition pathways and intermediate conformations in sub-mesoscopic protein complexes

open access: yesNature Communications
Protein conformational changes are the cornerstone of biological function. While conformers captured experimentally represent metastable states, the pathways connecting them have been elusive for experiments and simulations alike.

Vein fate determined by flow-based but time-delayed integration of network architecture

open access: yeseLife, 2023
Veins in vascular networks, such as in blood vasculature or leaf networks, continuously reorganize, grow or shrink, to minimize energy dissipation. Flow shear stress on vein walls has been set forth as the local driver for a vein’s continuous adaptation.

Protein folding tames chaos [PDF]

open access: yes, 2013
Protein folding produces characteristic and functional three-dimensional structures from unfolded polypeptides or disordered coils. The emergence of extraordinary complexity in the protein folding process poses astonishing challenges to theoretical ...

Probing protein-protein interactions by dynamic force correlated spectroscopy (FCS)

open access: yes, 2005
We develop a formalism for single molecule dynamic force spectroscopy to map the energy landscape of protein-protein complex ($P_1$$P_2$). The joint distribution $P(\tau_1,\tau_2)$ of unbinding lifetimes $\tau_1$ and $\tau_2$ measurable in a compression ...

Pyrone-based inhibitors of metalloproteinase types 2 and 3 may work as conformation-selective inhibitors. [PDF]

open access: yes, 2011
Matrix metalloproteinases are zinc-containing enzymes capable of degrading all components of the extracellular matrix. Owing to their role in human disease, matrix metalloproteinase have been the subject of extensive study.

Resolving Protein Structure Dynamically [PDF]

open access: yesStructure, 2005
In this issue of Structure, Rajagopal et al. (2005) report further innovations in the X-ray diffraction analysis of the dynamical changes in protein conformation; they use these methods to resolve the light-activated changes in the conformation of Photoactive Yellow Protein. This approach allows a straightforward reinforcement of X-ray diffraction data

The absence of SOX2 in the anterior foregut alters the esophagus into trachea and bronchi in both epithelial and mesenchymal components

open access: yesBiology Open, 2020
In the anterior foregut (AFG) of mouse embryos, the transcription factor SOX2 is expressed in the epithelia of the esophagus and proximal branches of respiratory organs comprising the trachea and bronchi, whereas NKX2.1 is expressed only in the epithelia

Stochastic single-molecule dynamics of synaptic membrane protein domains

open access: yes, 2016
Motivated by single-molecule experiments on synaptic membrane protein domains, we use a stochastic lattice model to study protein reaction and diffusion processes in crowded membranes.

Molecular Dynamics Studies on the Buffalo Prion Protein [PDF]

open access: yes, 2015
It was reported that buffalo is a low susceptibility species resisting to prion diseases, which are invariably fatal and highly infectious neurodegenerative diseases that affect a wide variety of species.

Quantitative Protein Dynamics from Dominant Folding Pathways

open access: yes, 2007
We develop a theoretical approach to the protein folding problem based on out-of-equilibrium stochastic dynamics. Within this framework, the computational difficulties related to the existence of large time scale gaps in the protein folding problem are ...
