iCLIP of FXR1-WT and FXR1-V361P in HeLa cells
In the associated paper FXR1 is shown to package exceptionally long mRNAs in the cytoplasm and organizes them into an mRNP network. We performed iCLIP of FXR-WT and its mutant FXR1-V361P in HeLa cells where we knocked down endogenous FXR1 and replaced it with either GFP-tagged WT or V361P-mutant FXR1. The GFP-tagged proteins were immunoprecipitated using an anti-GFP antibody.
