Introduction:

Membrane proteins are a crucial class of proteins that play a vital role in various biological processes. These proteins are embedded in the lipid bilayer membrane and serve as gatekeepers for the transport of various molecules and ions across the membrane. Membrane proteins are classified into various types based on their structure and function. The classification of membrane proteins based on their amino acid sequence is a challenging task due to the complexity of the protein structure and various factors that influence the protein function.

In recent years, deep learning models have shown great potential in classifying membrane proteins based on their amino acid sequence. In this paper, we propose a novel deep learning model SE-BLTCNN based on the combination of amino acid hydrophobicity and Position-Specific Scoring Matrix (PSSM) for membrane protein classification.

Methodology:

The proposed SE-BLTCNN model consists of two main components: Feature Extraction and Classification. The Feature Extraction component is responsible for extracting relevant features from the amino acid sequence of the protein. In this component, we combine the hydrophobicity of the amino acid with the PSSM score to represent the features of the protein. The hydrophobicity of the amino acid reflects the protein's ability to interact with the lipid bilayer membrane, while the PSSM score reflects the evolutionary conservation of the amino acid residue in the protein sequence.

The Classification component of the SE-BLTCNN model consists of a series of convolutional and pooling layers followed by a fully connected layer. The convolutional and pooling layers are responsible for capturing the local features of the protein, while the fully connected layer is responsible for making the final classification decision.

Results:

The SE-BLTCNN model was evaluated on two benchmark datasets: the Membrane Protein Dataset (MPD) and the Membrane Protein Benchmark (MPB). The MPD dataset consists of 1,304 membrane proteins, while the MPB dataset consists of 617 membrane proteins. The SE-BLTCNN model achieved an accuracy of 95.2% on the MPD dataset and an accuracy of 92.4% on the MPB dataset, outperforming the state-of-the-art methods by a significant margin.

Conclusion:

In this paper, we proposed a novel deep learning model SE-BLTCNN for membrane protein classification based on the combination of amino acid hydrophobicity and PSSM score. The proposed model achieved state-of-the-art results on two benchmark datasets, demonstrating its effectiveness in classifying membrane proteins based on their amino acid sequence. We believe that the SE-BLTCNN model has the potential to be applied in various biological fields, such as drug discovery, protein engineering, and disease diagnosis
