Researchers develop AI tool to map microRNA binding sites on circular RNAs
Circular RNAs (circRNAs) are loop-shaped molecules that can influence gene regulation through interactions with microRNAs (miRNAs). This matters because circRNAs can exist as different full-length isoforms, and their back-splice junction (BSJ) connects the two ends of the RNA. Tr
