TY - JOUR T1 - Predicting protein-membrane interfaces of peripheral membrane proteins using ensemble machine learning JF - bioRxiv DO - 10.1101/2021.06.28.450157 SP - 2021.06.28.450157 AU - Alexios Chatzigoulas AU - Zoe Cournia Y1 - 2021/01/01 UR - http://biorxiv.org/content/early/2021/10/23/2021.06.28.450157.abstract N2 - Abnormal protein-membrane attachment is involved in deregulated cellular pathways and in disease. Therefore, the possibility to modulate protein-membrane interactions represents a new promising therapeutic strategy for peripheral membrane proteins that have been considered so far undruggable. A major obstacle in this drug design strategy is that the membrane binding domains of peripheral membrane proteins are usually not known. The development of fast and efficient algorithms predicting the protein-membrane interface would shed light into the accessibility of membrane-protein interfaces by drug-like molecules. Herein, we describe an ensemble machine learning methodology and algorithm for predicting membrane-penetrating amino acids. We utilize available experimental data in the literature for training 21 machine learning classifiers and a voting classifier. Evaluation of the ensemble classifier accuracy produced a macro-averaged F1 score = 0.92 and an MCC = 0.84 for predicting correctly membrane-penetrating amino acids on unknown proteins of an independent test set. The python code for predicting protein-membrane interfaces of peripheral membrane proteins is available at https://github.com/zoecournia/DREAMM.Competing Interest StatementThe authors have declared no competing interest.
