BERT-HemoPep60
A deep learning method based on transformer architecture and Domain Adaptive Pre-Training (DAPT) for quantitative prediction of peptide hemolytic activity against human red blood cells.
Overview
BERT-HemoPep60 is a deep learning method based on transformer architecture and Domain Adaptive Pre-Training (DAPT) for quantitative prediction of peptide hemolytic activity against human red blood cells. The model employs an innovative prefix prompting approach that integrates experimental hemolysis data from six common mammalian species (human, mouse, rat, horse, sheep, and rabbit) and multiple hemolysis indicators (HC5, HC10, HC50) for peptide toxicity prediction.
Model Performance
We employed an innovative prefix prompting approach to integrate experimental data from six mammalian species into a single model, significantly improving prediction accuracy. Compared to traditional methods, BERT-HemoPep60 achieves excellent performance across various metrics.
Results Interpretation
BERT-HemoPep60 provides three key hemolytic activity indicators:
- HC5: Represents the peptide concentration (μM) required to cause 5% hemolysis of red blood cells
- HC10: Represents the peptide concentration (μM) required to cause 10% hemolysis of red blood cells
- HC50: Represents the peptide concentration (μM) required to cause 50% hemolysis of red blood cells
Important Note: Lower HC values indicate stronger hemolytic activity (higher toxicity), while higher HC values indicate weaker hemolytic activity (lower toxicity).
