Unnatural Amino Acid and Emerging Chemistry Approaches to Map RNA–Protein Interactions
Angewandte Chemie, EarlyView.This review highlights emerging chemistries for mapping RNA–protein interactions, including genetically encoded unnatural amino acids, novel photocrosslinkers, and non‐photoactivatable crosslinking systems. We compare their mechanisms, reactivity and applications, outlining how these next‐generation tools enable higher‐resolution, site‐specific ...
