Background:

Epitopes are crucial for understanding immune system interactions between antigens and antibodies.
Experimental identification of linear B-cell epitopes (BCEs) is resource-intensive and low-throughput.
Existing computational methods for BCE prediction require further development for practical use.

Purpose of the Study:

To make a user-friendly prediction tool accessible to the scientific community.

Main Methods:

A deep learning architecture integrating bi-directional long short-term memory (Bi-LSTM), feed-forward attention, and multi-scale convolutional neural networks (CNNs) was employed.
The model, named DeepLBCEPred, was rigorously evaluated using cross-validation and independent testing on multiple datasets.
The contribution of individual deep learning components to prediction accuracy was analyzed.

Main Results:

DeepLBCEPred achieved state-of-the-art performance in predicting linear B-cell epitopes.
Empirical results from extensive testing demonstrated the model's high accuracy and reliability.
Analysis confirmed the effectiveness of the combined deep learning elements in epitope recognition.

Conclusions:

DeepLBCEPred represents a significant advancement in computational epitope prediction.
The developed tool offers a practical and efficient solution for identifying linear BCEs.
