在模式生物中发现RNA编辑位点,除了发现调节神经活性的潜在位点之外,还可以深入了解它们的适应性,并为后生动物编辑的综合模型提供基础,这些模型具有多种应用,包括神经失调的潜在临床治疗。斑马鱼是一种重要的脊椎动物模式系统。由于斑马鱼grin1b基因作为谷氨酸受体在神经组织中的重要功能,我们将重点放在了它的基因上。使用比较序列为基础的方法,我们找到了可能的RNA编辑事件内的grin1b转录。令人惊讶的是,序列分析还揭示了一个新的编辑位点,这是没有预测的比较方法。我们在这里报告发现两个新的RNA编辑事件在胚胎斑马鱼的GRIN1B转录本。这些编辑事件的频率和它们在grin1b转录本中的位置也被描述。
Discovering RNA editing sites in model organisms provides an insight into their adaptations in addition to finding potential sites for the regulation of neural activity and the basis of integrated models of metazoan editing with a variety of applications, including potential clinical treatments of neural dysregulation. The zebrafish, Danio rerio, is an important vertebrate model system. We focused on the grin1b gene of zebrafish due to its important function in the nervous tissue as a glutamate receptor. Using a comparative sequence-based approach, we located possible RNA editing events within the grin1b transcript. Surprisingly, sequence analysis also revealed a new editing site which was not predicted by the comparative approach. We here report the discovery of two novel RNA editing events in grin1b transcripts of embryonic zebrafish. The frequency of these editing events and their locations within the grin1b transcript are also described.
