摘要
数据独立采集(DIA)是一项用于大规模蛋白质组学研究的新兴技术。DIA数据分析方法正在迅速发展,深度学习在这一领域已经崭露头角。涵盖领域:本文讨论并概述了用于DIA数据分析的深度学习方法,包括光谱库预测、特征评分、肽中心分析中的统计控制以及从头开始的肽测序。对截至2021年12月的PubMed、Scopus和Web of Science数据库中的文章(包括预印本)进行文献检索。专家意见:光谱文库预测虽然突破了实验文库对蛋白质组覆盖的限制,但由于查询空间大所带来的统计负担是利用全蛋白质组预测文库的剩余挑战。翻译后修饰分析是基于深度学习的DIA方法的另一个有前途的方向。
Deep learning approaches for data-independent acquisition proteomics.
Introduction: Data-independent acquisition (DIA) is an emerging technology for large-scale proteomic studies. DIA data analysis methods are evolving rapidly, and deep learning has cut a conspicuous figure in this field.
Areas covered: This review discusses and provides an overview of the deep learning methods that are used for DIA data analysis, including spectral library prediction, feature scoring, and statistical control in peptide-centric analysis, as well as de novo peptide sequencing. Literature searches were performed for articles, including preprints, up to December 2021 from PubMed, Scopus, and Web of Science databases.
Expert opinion: While spectral library prediction has broken through the limitation on proteome coverage of experimental libraries, the statistical burden due to the large query space is the remaining challenge of utilizing proteome-wide predicted libraries. Analysis of post-translational modifications is another promising direction of deep learning-based DIA methods.
