摘要

摘要

En 中文
DNA编码文库(DELs)通过拆分-混合合成和DNA标记技术,实现了对万亿级分子与蛋白质靶点的高通量筛选。尽管其潜力巨大,但仅有少数DEL衍生的化合物进入临床试验或上市。对靶蛋白特征,尤其是适合DEL筛选的结合口袋的深入理解,对于提高成功率至关重要。然而,现有方法在评估口袋柔韧性和功能相似性方面仍显局限。本研究提出ErePOC,一种基于对比学习与ESM-2嵌入的口袋表征模型,以应对这些挑战。ErePOC能够捕捉结合口袋的结构与功能特征,从而识别DEL靶点间的共有特性。通过整合低维理化性质分析与高维ErePOC嵌入分析,我们提供了对DEL靶点空间的全面视角。在下游分类任务中达到98%的精度,ErePOC在口袋表征方面表现出高性能,并应用于预测适合DEL筛选的人类蛋白质,在18个功能类别中均显示出富集现象。本研究建立了一个通过更有效的靶点选择和口袋相似性分析来增强DEL药物发现的框架。DNA编码文库(DELs)在药物发现中具有前景,但由于对靶点兼容性的理解有限,其表现往往不尽如人意。本研究提出ErePOC,一种能够识别适合DEL筛选的蛋白质口袋的口袋表征模型。
