摘要
迄今为止,虚拟筛选(VS)通常采用基于结构的药物设计模式。这种方法通常需要在目标蛋白质的高分辨率三维结构上进行分子对接--计算密集且耗时。这项研究表明,将蛋白质语言模型和分子图作为新型图-转换器交叉注意机制的输入,可以实现与最先进的基于结构的模型相媲美的筛选能力。由于运行该模型所需的计算量大大减少,因此可以大大加快 VS 的速度,并能在完全没有三维蛋白质结构的情况下进行早期阶段的计算机辅助药物设计。
Protein language models are performant in structure-free virtual screening.
Hitherto virtual screening (VS) has been typically performed using a structure-based drug design paradigm. Such methods typically require the use of molecular docking on high-resolution three-dimensional structures of a target protein-a computationally-intensive and time-consuming exercise. This work demonstrates that by employing protein language models and molecular graphs as inputs to a novel graph-to-transformer cross-attention mechanism, a screening power comparable to state-of-the-art structure-based models can be achieved. The implications thereof include highly expedited VS due to the greatly reduced compute required to run this model, and the ability to perform early stages of computer-aided drug design in the complete absence of 3D protein structures.
