The somatic hypermutation (SHM) of Immunoglobulin variable (V) regions is a key process in the generation of antibody diversity. The growing number of datasets of point mutations that occur during SHM in mice and humans often include comparisons between wild-type and individuals or strains genetically defective in the repair mechanisms that contribute to SHM. However, it has been difficult to compare the results of different studies because the analyses have not been standardized for criteria such as correction for base composition and the inclusion of unique mutations. If many mutations are involved, the analysis can also be time consuming. To overcome these problems and facilitate a standardized analysis and display of similar data, we present a webserver (SHMTool) for comparing SHM datasets, available at http://scb.aecom.yu.edu/shmtool.
免疫球蛋白可变区的体细胞高频突变(SHM)是产生抗体多样性的关键过程。在小鼠和人类的SHM过程中发生的点突变数据集越来越多,其中常常包括野生型与在对SHM有贡献的修复机制上存在基因缺陷的个体或品系之间的比较。然而,由于分析在诸如碱基组成校正和独特突变纳入等标准方面未实现标准化,因此难以比较不同研究的结果。如果涉及许多突变,分析也可能很耗时。为克服这些问题并便于对类似数据进行标准化分析和展示,我们推出了一个用于比较SHM数据集的网络服务器(SHMTool),可在http://scb.aecom.yu.edu/shmtool获取。
