Promoters have diverse regulatory architectures and thus activate genes differently. For example, some have a TATA-box, many others do not. Even the ones with it can differ in its position relative to the transcription start site (TSS). No Promoter Left Behind (NPLB) is an efficient, organism-independent method for characterizing such diverse architectures directly from experimentally identified genome-wide TSSs, without relying on known promoter elements. As a test case, we show its application in identifying novel architectures in the fly genome.

启动子具有多样的调控结构,因此以不同方式激活基因。例如,有些启动子有TATA框,而许多其他启动子则没有。即使是有TATA框的启动子,其相对于转录起始位点(TSS)的位置也可能不同。“一个都不能少”(NPLB)是一种高效的、不依赖生物体的方法,可直接从实验确定的全基因组TSS中表征这种多样的结构,而无需依赖已知的启动子元件。作为一个测试案例,我们展示了它在鉴定果蝇基因组中新型结构方面的应用。
