In this study, Vo ngoc et al. used machine learning to compare the downstream core promoter (DPR) region, a DNA motif within the core promoter involved in transcription initiation, in humans and Drosophila. They identify synthetic DPR variants with specificity for species-specific transcription factors and discuss implications of their synthetic variant modeling strategy in the functional annotation of DNA sequence elements. The RNA polymerase II core promoter is the site of convergence of the signals that lead to the initiation of transcription. Here, we performed a comparative analysis of the downstream core promoter region (DPR) in Drosophila and humans by using machine learning. These studies revealed a distinct human-specific version of the DPR and led to the use of machine learning models for the identification of synthetic extreme DPR motifs with specificity for human transcription factors relative to Drosophila factors and vice versa. More generally, machine learning models could similarly be used to design synthetic DNA elements with customized functional properties.
