Each element of the Drosophila tRNAArg gene split promoter directs transcription in Xenopus oocytes.

abstract：:The diverse localization of transcripts in cells suggests that there are many specific RNA-protein interactions that have yet to be identified. Progress has been limited, however, by the lack of a robust method to detect and isolate the RNA-binding proteins. Here we describe the use of an RNA aptamer, scaffolded to a ...
