Hundreds of ribosomal … WebbRibosome biogenesis, involving the de novo synthesis of ribosomes, is a complex and essential process within cells, including transcription and processing of ribosomal RNA, production of ribosomal proteins, and assembly of nuclear export of ribosomal subunits. Biogenesis in eukaryotes is complex and depends on more than 200 assembly factors. WebbIn eukaryotes, however, fundamental differences-such as the rarity of polycistronic mRNAs and different chaperone constellations-raise the question of whether assembly is also coordinated with translation. Here we provide a systematic and mechanistic analysis of the assembly of protein complexes in eukaryotes using ribosome profiling. condition translate
