Conserved Binding Sites

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...

Directing Proteins to the Rough Endoplasmic Reticulum

Directing Proteins to the Rough Endoplasmic Reticulum

The organelle-specific signaling sequences direct proteins synthesized in the cytosol to their final destination like ER, mitochondria, peroxisomes, etc. Some of the proteins directed to ER are then trafficked via vesicles to other organelles within the cell or the extracellular environment through the Golgi complex. For example, the rough ER synthesizes soluble proteins for transportation to the lysosomes or secretion out of the cell. It can also synthesize transmembrane proteins that can...

Background:

Antibodies are crucial in research and biotechnology, with specificity dictated by antigen epitope interactions.
Predicting epitopes from sequence data can streamline experimental efforts.
This work builds upon prior sequence-based predictors for protein-protein interaction (PPI) interfaces.

Purpose of the Study:

To develop and validate a sequence-based predictor for identifying antibody-binding epitope residues.
To improve upon existing methods for epitope prediction using machine learning.

Main Methods:

Curated a high-quality epitope dataset from the SAbDab database.
Trained random forest models using sequence data, including generic PPI and specific epitope datasets.
Evaluated predictor performance using AUC-ROC metrics.

Main Results:

A specialized random forest model achieved an AUC of 0.694 on the epitope test set.
Combining datasets improved the predictor to an AUC of 0.703, outperforming BepiPred-2.0.
The predictor demonstrated strong performance on a COVID-19 spike protein structure (AUC 0.778).

Conclusions:

The developed sequence-based predictor effectively identifies potential antibody-binding epitopes.
The SeRenDIP-CE Conformational Epitope predictors are available via a user-friendly webserver.
This tool facilitates antibody-antigen research in various biomedical applications.
