组蛋白修饰的全基因组作图对于理解转录调控至关重要。CUT&Tag是一种用于分析组蛋白修饰的新方法,与ChIP-seq相比,具有更高的灵敏度和更低的成本。在这里,我们提出了GoPeaks,一个专门为组蛋白修饰CUT&Tag数据设计的峰调用方法。我们将GoPeaks的性能与常用的峰调用算法进行比较,以检测显示一系列峰轮廓并经常用于表观遗传学研究的组蛋白修饰。我们发现GoPeaks可以稳健地检测全基因组组的组蛋白修饰,并且值得注意的是,与其他标准算法相比,它识别了大量的H3 K27 ac峰,并且灵敏度有所提高。在线版本包含补充材料,可通过10.1186/s13059-022-02707-w获得。
Genome-wide mapping of histone modifications is critical to understanding transcriptional regulation. CUT&Tag is a new method for profiling histone modifications, offering improved sensitivity and decreased cost compared with ChIP-seq. Here, we present GoPeaks, a peak calling method specifically designed for histone modification CUT&Tag data. We compare the performance of GoPeaks against commonly used peak calling algorithms to detect histone modifications that display a range of peak profiles and are frequently used in epigenetic studies. We find that GoPeaks robustly detects genome-wide histone modifications and, notably, identifies a substantial number of H3K27ac peaks with improved sensitivity compared to other standard algorithms.
