# ProtBERT-Unmasking
|
| 17 |
|
| 18 |
This model is a fine-tuned version of ProtBERT specifically optimized for unmasking protein sequences. It can predict masked amino acids in protein sequences based on the surrounding context.
|
|
|
|
| 23 |
- **Task**: Protein Sequence Unmasking
|
| 24 |
- **Training**: Fine-tuned on masked protein sequences
|
| 25 |
- **Use Case**: Predicting missing or masked amino acids in protein sequences
|
| 26 |
+
- **Optimal Use**: Best performance on E. coli sequences with known amino acids K, C, Y, H, S, M
|
| 27 |
+
|
| 28 |
+
For detailed information about the training methodology and approach, please refer to our paper:

## Usage
|
| 32 |
|
|
|
|
| 34 |
from transformers import AutoModelForMaskedLM, AutoTokenizer
|
| 35 |
|
| 36 |
# Load model and tokenizer
|
| 37 |
+
model = AutoModelForMaskedLM.from_pretrained("your-username/protbert-sequence-unmasking")
|
| 38 |
+
tokenizer = AutoTokenizer.from_pretrained("your-username/protbert-sequence-unmasking")
|
| 39 |
|
| 40 |
+
# Example usage for E. coli sequence with known amino acids (K,C,Y,H,S,M)
|
| 41 |

```
|
| 46 |
|
| 47 |
+
## Inference API
|
| 48 |
+
|
| 49 |
+
The model is optimized for:
|
| 50 |
+
- **Organism**: E. coli
|
| 51 |
+
- **Known Amino Acids**: K, C, Y, H, S, M
|
| 52 |
+
- **Task**: Predicting unknown amino acids in a sequence
|
| 53 |
+
|
| 54 |
+
Example API usage:
|
| 55 |
+
```python
|
| 56 |
+
from transformers import pipeline
|
| 57 |
+
|
| 58 |
+
unmasker = pipeline('fill-mask', model='your-username/protbert-sequence-unmasking')
|
| 59 |
+
sequence = "K[MASK]YHS[MASK]" # Example with known amino acids K,Y,H,S
|
| 60 |
+
results = unmasker(sequence)
|
| 61 |
+
|
| 62 |
+
for result in results:
|
| 63 |
+
print(f"Predicted amino acid: {result['token_str']}, Score: {result['score']:.3f}")
|
| 64 |
+
```
|
| 65 |
+
|
| 66 |
## Limitations and Biases
|
| 67 |
|
| 68 |
+
- This model is specifically designed for protein sequence unmasking in E. coli
|
| 69 |
+
- Optimal performance is achieved when working with sequences containing known amino acids K, C, Y, H, S, M
|
| 70 |
+
- The model may not perform optimally for:
|
| 71 |
+
- Sequences from other organisms
|
| 72 |
+
- Sequences without the specified known amino acids
|
| 73 |
+
- Other protein-related tasks
|
| 74 |
|
| 75 |
