library_construction_protocol: Immunoprecipitations with TAP-tagged Mrd1 proteins were performed with TNM150 buffer (50 mM Tris-HCl pH 7.8, 1.5 mM MgCl2, 150 mM NaCl, 0.1% NP-40 and 5 mM b-mercaptoethanol), essentially as previously described (Granneman et al., 2009). RNA was extracted using a GTC phenol solution (4 M guanidine thiocyanate, 0.05 M Tris at pH 8.0, 0.01 M EDTA, 2% sarcosyl, 1% β-mercaptoethanol, 50% [v/v] phenol) as previously described (Sambrook, 1989). cDNA libraries were generated from purified ribosomal RNA using an RT oligonucteotide containing random hexamers (SuperScript III, Invitrogen). 5' adapters were ligated on (CircLigase II, EpiCentre) and 3' adaptors generated during PCR amplification.
