Promoter is a short region of DNA which is responsible for initiating transcription of specific genes. Development of computational tools for automatic identification of promoters is in high demand. According to the difference of functions, promoters can be of different types. Promoters may have both intra- and interclass variation and similarity in terms of consensus sequences. Accurate classification of various types of sigma promoters still remains a challenge.

iPromoter-BnCNN：一种新颖的基于CNN分支的预测器，用于识别和分类Sigma启动子。

启动子是DNA的短区域，负责启动特定基因的转录。迫切需要开发用于自动识别启动子的计算工具。根据功能的不同，启动子可以是不同类型的。启动子在共有序列方面可能具有类内和类间变异和相似性。各种类型的sigma启动子的准确分类仍然是一个挑战。
