Updated project metadata. 1.0 – 1.3 x 10e8 proliferating Jurkat cells at a density of about 1-1.5 x 10e6 cells/mL were employed per sample. Cells were incubated with 0.5mM DMOG (Cayman Chemical Company, 71210) or an equivalent volume of Dimethyl Sulfoxide (DMSO) (vehicle, Merck 1.02950.0500). The DMSO concentration in the medium was 0.023% v/v. Cells were irradiated or not with 254 nm UV light and subjected to eRIC or RIC to determine the RNA-bound proteome. Data correspond to two biologically independent experiments.
