- Bioinformatics
Background:
- DNA-binding proteins are essential for cellular functions.
- Accurate identification of DNA-binding proteins is critical for genome annotation.
- Existing methods require enhancement for improved prediction power.
Purpose of the Study:
- To develop a novel, high-throughput computational tool for identifying DNA-binding proteins.
- To enhance the prediction accuracy of DNA-binding proteins using sequence information alone.
- To provide a user-friendly web server for public access.
Main Methods:
- Incorporated features from the 'grey model' into pseudo amino acid composition.
- Utilized the random forest algorithm for classification.
- Developed a stringent benchmark dataset with low sequence identity.
Main Results:
- The iDNA-Prot predictor achieved an overall success rate of 83.96% via jackknife tests.

Labeling DNA Probes
DNA probes are fragments of DNA labeled with a reporter tag to enable their detection or purification. The resulting labeled DNA probes can then hybridize to target nucleic acid sequences through complementary base-pairing, and may be used to recover or identify these regions.
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...

Conserved Binding Sites
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 analyses the...

Protein-protein Interfaces
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 polypeptide...
