By studying the processing of pri-miR-9 family, Bofill-De Ros et al. demonstrate that the tertiary structure of pri-miRNA triggers alternative biogenesis. Drosha cleaves pri-miR-9-1 at an additional site because of its distorted and flexible lower stem, generating a 5′ isomiR that regulates a distinct set of genes in low-grade glioma.
