Protein-protein Interfaces02:04

Protein-protein Interfaces

14.7K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes. Two different solutions can differ in their hydronium or hydroxide ion concentrations by a million, billion, or even trillion times. A common means of...

Protein Networks

4.6K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Network Covalent Solids

16.2K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Area of Science:

  • Computational Neuroscience
  • Systems Neuroscience
  • Biophysics

Background:

  • Large-scale network models are crucial for understanding neuronal activity and computations in neuroscience.
  • Existing simulators like NEURON and NEST face challenges in data-driven, large-scale modeling setup and execution.

Purpose of the Study:

  • To develop a high-level Python API (BioNet) for simplifying the construction and simulation of large-scale, biophysically detailed neural networks.
  • To facilitate data integration and streamline the modeling workflow for neuroscientists.

Main Methods:

  • Developed a Python API, BioNet, providing a high-level interface for building neural network models.
  • Integrated BioNet with the NEURON simulator for execution on parallel computing architectures.
  • Supported modular workflows with standardized file saving for model refinement and reuse.
  • Enabled the use of both built-in and user-defined cell and synapse models within NEURON.

Main Results:

  • BioNet simplifies the creation of complex neural network models, reducing the need for custom coding.
  • The API supports simulation of standard NEURON observables (spikes, membrane voltage, intracellular calcium) and extensible observables (e.g., extracellular potential).
  • Model descriptions are saved in standardized files, promoting model sharing and reproducibility.

Conclusions:

  • BioNet significantly lowers the barrier to entry for large-scale neural network modeling.
  • The tool empowers neuroscientists to focus on scientific questions rather than intricate simulation code development.
  • BioNet enhances collaboration and accelerates discovery in computational neuroscience.
