Zotatifin promotes eIF4A binding to specific mRNA sequences and interferes with the assembly of the eIF4F initiation complex. It results in translational regulation of oncogenic protein … WebbRibosomes are evolutionary-conserved molecular machines consisting of the large 60S and the small 40S subunits, which follow separate assembly routes but later function together as mature 80S ribosomes during translation. During ribosome biogenesis the pre-60S subunit goes through many maturation steps that require numerous assembly factors.

WebbDefects in ribosome biogenesis and function are present in a growing list of human syndromes associated with cancer susceptibility. One example is X-linked dyskeratosis congenita (X-DC) in which the DKC1 gene, encoding for an enzyme that modifies ribosomal RNA, is found to be mutated.
WebbOur current thinking is that factors that aid in ribosome biogenesis fall into two broad classes. First, the RNA helicases, nucleases and chaperones shape and mould the rRNA into its final shape. These proteins utilize the energy liberated from ATP hydrolysis to exert structural rearrangements (Fig. 1B).
