G quadruplex structures play an important role in regulating DNA replication and transcription and mRNA translation. Although there are several techniques that can determine its formation in vitro, the study of RNA G quadruplexes in vivo is not simple. In the current protocol, we describe an optimized technique (RNA G quadruplex immunoprecipitation [rG4IP]) to selectively pull down native cytoplasmic RNAs containing G quadruplex structures in mammalian cells. We also use a bicistronic plasmid to confirm and pinpoint the structure location.

For complete details on the use and execution of this protocol, please refer to Surani et al. (2022).
