Webb10 juni 2024 · Ribosome biogenesis is a central process in every growing cell. In eukaryotes, it requires more than 250 non-ribosomal assembly factors, most of which are essential. Despite this large repertoire of potential targets, only very few chemical inhibitors of ribosome biogenesis are known so far. Webb1 nov. 2013 · The 80S ribosome (named for its apparent sedimentation velocity) is a ribonucleoprotein complex that comprises two ribosomal subunits, a large 60S subunit [containing the 25S, 5.8S and 5S rRNA, and 46 ribosomal proteins (r-proteins)] and a small 40S subunit (containing the 18S rRNA and 33 r-proteins) ( Fromont-Racine et al., 2003; …
