Updated project metadata. RRP41 is one of the nine subunits constituting the core complex of the eukaryotic RNA exosome. Data presented here allowed a proteomic characterization of the interactome of wild type or mutated myc-tagged RRP41 proteins incorporated into the RNA exosome. Flowers from myc-tagged RRP41 expressing lines were used to affinity purify RNA exosomes, which were analyzed by nanoLC-MS/MS analysis. Non-transgenic Arabidopsis lines of Col-0 accession were used in mock-immunoprecipitation experiments as negative controls.
