Executive Industry Relevance

Mapping transcript architecture from the 3' end into coding regions enables precise characterization of mRNA isoforms, a critical step in target validation for oncology drug discovery. By identifying tumor-specific fusion genes and splice variants, this method supports mechanistic de-risking and improves predictive confidence in early-stage target selection. The approach enhances translational continuity by linking molecular findings to functional transcript stability elements such as miRNA binding sites and AU-rich regions.
