Ligand Binding Sites02:40

Ligand Binding Sites

12.7K
Proteins are dynamic macromolecules that carry out a wide variety of essential processes; however, the activities of most proteins depend on their interactions with other molecules or ions, known as ligands.
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...

The Equilibrium Binding Constant and Binding Strength

12.8K
The equilibrium binding constant (Kb) quantifies the strength of a protein-ligand interaction. Kb can be calculated as follows when the reaction is at equilibrium:

Survival Tree01:19

Survival Tree

61
Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Protein-protein Interfaces02:04

Protein-protein Interfaces

12.5K
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...

Conserved Binding Sites01:49

Conserved Binding Sites

4.2K
Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function.
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally...

Area of Science:

  • Computational biology
  • Bioinformatics
  • Systems biology

Background:

  • Ligand-receptor interactions (LRIs) are crucial for understanding cell-to-cell communication in biological and medical research.
  • Experimental discovery of new LRIs is often expensive and time-consuming.

Purpose of the Study:

  • To develop a computational model, THGB, for accurate and efficient prediction of novel ligand-receptor interactions (LRIs).
  • To provide a cost-effective tool for inferring cell-to-cell communication.

Main Methods:

  • THGB utilizes iFeature for extracting feature information from ligand-receptor (LR) pairs.
  • A tree boosting model is employed for selecting representative LR features.
  • A histogram-based gradient boosting model is used to predict high-quality LRIs.

Main Results:

  • THGB demonstrated superior performance compared to existing LRI prediction models (CellEnBoost, CellGiQ, CellComNet) and a protein-protein interaction model (PIPR) across six evaluation metrics.
  • Feature selection using the tree boosting model proved more effective than PCA, NMF, LLE, and TSVD for LRI prediction.
  • An ablation study confirmed that THGB with feature selection yields better results than without.

Conclusions:

  • THGB is a highly effective computational tool for predicting ligand-receptor interactions.
  • The model's feature selection strategy enhances LRI prediction accuracy.
  • THGB offers a valuable resource for discovering new LRIs and advancing the study of cell-to-cell communication.
