A research team has developed a deep learning model named PATHpre to predict protein conformational changes, recently published in Advanced Science. This model addresses the challenge of predicting dynamic protein behaviors, which are crucial for understanding protein functions. By integrating a coarse-grained molecular dynamics model with enhanced sampling methods, the team created a framework that simulates the conformational changes of thousands of proteins.
The PATHpre model not only predicts transition states but also the entire pathways of conformational changes, offering significant insights into protein dynamics. Validation against experimental data revealed its effectiveness, even uncovering a novel allosteric regulation mechanism in human β-cardiac myosin. This advancement could lead to breakthroughs in therapeutic development for diseases related to protein misfolding.
• PATHpre model predicts protein dynamics and conformational changes effectively.
• Model reveals novel allosteric regulation mechanism in human β-cardiac myosin.
Deep learning is a subset of machine learning that uses neural networks to analyze data patterns.
Conformational changes refer to the alterations in the structure of proteins that affect their function.
Allostery is a regulatory mechanism where the binding of a molecule at one site affects the activity at another site.
USTC is involved in advanced scientific research, contributing to the development of the PATHpre model.
ShanghaiTech University collaborates in research efforts to enhance understanding of protein dynamics.
