Stage-specific assembly of nucleolar pre-60S particles. (A) SYPRO-Ruby-stained SDS-PAGE gel of preribosomal complexes corresponding to increasing length of large subunit pre-RNA. Ribosome assembly factors are indicated on the right. (B) LC-MS analysis of ribosome assembly factors, based on a triplicate of samples, normalized against Cic1 and classified by recruitment stage. Protein abundance is measured by peak area, and high abundance proteins are shown in orange/red while low abundance and absent proteins are shown in black/gray. (C) LC-MS analysis of the polyadenylate-binding protein (PABP), Smt3, and the H/ACA and box C/D snoRNP proteins.
