Area of Science:

Bioinformatics
Computational Biology
Virology

Background:

Hemagglutinin (HA) is crucial for influenza virus entry and infection.
HA is a significant target for developing influenza antiviral drugs and vaccines.
Current in-silico methods for HA identification are limited.

Purpose of the Study:

To design and develop a computational model for accurate in-silico identification of hemagglutinin (HA).
To facilitate targeted vaccine and drug development against influenza.

Main Methods:

A benchmark dataset of 106 HA and 106 non-HA sequences was curated from UniProt.
Sequence-based features were extracted and optimized.
An integrated classifier model was constructed using a stacking algorithm with four machine learning methods.

Main Results:

The model achieved 95.85% accuracy and an ROC curve area of 0.9863 in 5-fold cross-validation.
In independent testing, the model demonstrated 93.18% accuracy and an ROC curve area of 0.9793.
The developed model shows excellent prediction performance.

Conclusions:

The proposed computational model provides an effective tool for HA identification.
This tool can assist biochemical researchers in studying HA and developing influenza therapeutics.
