Protein-protein Interfaces02:04

Protein-protein Interfaces

15.0K
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...

Protein Networks02:26

Protein Networks

4.7K
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,...

RNA Interference01:23

RNA Interference

28.6K
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

Nucleic Acids

52.0K
Nucleic acids are the most important macromolecules for the continuity of life. They carry the cell's genetic blueprint and carry instructions for its functioning.
DNA and RNA
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria. In prokaryotes,...

Area of Science:

  • Computational Biology
  • Bioinformatics
  • Structural Biology

Background:

  • Predicting RNA-binding sites in proteins is established, but the inverse problem of identifying protein-binding sites in RNA is less explored.
  • Existing protein-centric methods often neglect the role of interaction partners in RNA binding.

Main Methods:

  • Development of a web server named PRIdictor (Protein-RNA Interaction predictor).
  • Utilizes sequence-based information to predict binding sites.
  • Predicts interactions at both nucleotide-level resolution for RNA and residue-level resolution for protein.

Main Results:

  • PRIdictor successfully predicts mutual binding sites in RNA and protein.
  • The tool operates at nucleotide and residue levels, offering detailed interaction predictions.
  • Provides a web-based application and web service for accessibility.
