Protocol to study the role of a human nuclear m6A RNA reader on chromatin-associated RNA targets

Here, we present a detailed protocol to study the role of a human nuclear m6A RNA reader, YTHDC1, on chromatin-associated RNA targets. We describe steps for RNA extraction coupled to subnuclear fractionation to identify and study RNA-based regulations that take place in the chromatin-associated fraction. We then detail an RNA immunoprecipitation procedure adapted to identify chromatin-associated RNA targets. This protocol can be adapted to other human or mammalian chromatin-associated RNA binding proteins. For complete details on the use and execution of this protocol, please refer to Timcheva et al.(1)
