5-Ethynyluridine can be used to label newly synthesized RNA. This approach, named capture of the newly transcribed RNA interactome using click chemistry (RICK), systematically captures proteins bound to a wide range of RNAs, including nascent RNAs and traditionally neglected nonpolyadenylated RNAs.

Description | 5-Ethynyluridine is a clickable form of uridine.1It is incorporated into cellular RNA, but not DNA, and has been used to detect transcriptionin vitroandin vivo. 1.Jao, C.Y., and Salic, A.Exploring RNA transcription and turnover in vivo by using click chemistryProc. Natl. Acad. Sci. USA105(41)15779-15784(2008) |
In vivo | EU labelling can be used to examine transcription in vivo in mouse models of nervous system disorders. Injection of EU directly into the cerebellum results in reproducible labelling of newly transcribed RNA in cerebellar neurons and glia, with cell type-specific differences in relative labelling intensities, such as Purkinje cells exhibiting the highest levels. EU-labelling accumulating into cytoplasmic inclusions, indicating that EU, like other modified uridines, may introduce non-physiological properties in labelled RNAs[1]. |
