A wide variety of experimental techniques can be used for understanding the precise molecular mechanisms underlying the activities of cellular assemblies. The inherent limitations of a single experimental technique often requires integration of data from complementary approaches to gain sufficient insights into the assembly structure and function. Here, we review popular computational approaches for integrative modelling of cellular assemblies, including protein complexes and genomic assemblies. We provide recent examples of integrative models generated for such assemblies by different experimental techniques, especially including data from 3D electron microscopy (3D-EM) and chromosome conformation capture experiments, respectively. We highlight general concepts in integrative modelling and discuss the need for careful formulation and merging of different types of information.
可采用多种实验技术来了解细胞组装活动背后的精确分子机制。单一实验技术的固有局限性通常需要整合来自互补方法的数据,以充分了解组装结构和功能。在这里,我们综述了用于细胞组装(包括蛋白质复合物和基因组组装)综合建模的流行计算方法。我们提供了不同实验技术分别为这些组装体生成的综合模型的最新实例,特别是包括来自 3 维电子显微镜(3D-EM)和染色体构象捕获实验的数据。我们强调了综合建模中的一般概念,并讨论了仔细构建和合并不同类型信息的必要性。
