library_construction_protocol: Cells were lysed and treated with RNase I. GFP-tagged proteins were immunoprecipitated with Gamma binding beads coupled to goat anti-EGFP antibody (D. Drechsel, MPI-CBG). After stringent washing, RNA was dephosphorylated and ligated to a 3' linker. Protein-RNA complexes were resolved by denaturing gel electrophoresis and transfered to nitrocellulose membrane. A membrane region above the expected size of the protein was cut and RNA was released by Proteinase K treatment. RNA was reverse transcribed using reverse primer containing a barcode sequence. cDNA was separated into 3 size fractions by denaturing gel electrophoresis and circularized by ssDNA circligase. A specific oligonukelotide was annealed to create a restriction site for BamHI and cDNA was linearized by digest with BamHI. Linearized cDNA was PCR amplifiied with Solexa sequencing primers to create the final libraries. For more details see: König et al.
